readme: remove paragraph about executing clippy via "cargo run .."

This most likely no longer works since we are pinning clippy on a specific nightly now.
"cargo run" would try to compile clippy with whatever version the project we want to check demands.

Also building clippy yourself to run it on a project is not really needed anymore since clippy is shipped with official rust releases.

Fixes #6489

Added from_over_into lint

Closes #6456
Added a lint that searches for implementations of `Into<..>` and suggests to implement `From<..>` instead, as it comes with a default implementation of `Into`. Category: style.

12a35abba1 Auto merge of #6477 - xFrednet:0000-enable-search-with-dashes, r=ebroto
Adapted the website search for better matching

* This adds the ability to search for ids with dashes and spaces in the name.
    * Example: `missing-errors-doc` and `missing errors doc` are now valid aliases for lint names
* It also improves the fuzzy search in the description. This search will now match any lint that where all searched words are inside the description.
    * Example: `doc section` finds two lints in our selection

This was suggested/discussed on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Enable.20lint.20search.20with.20dashes/near/220469464)

### Testing
These changes can be tested locally by:
1. Clone this branch
2. Download the current lint index from the [gh-pages branch](https://github.com/rust-lang/rust-clippy/blob/gh-pages/master/lints.json)
3. Put it next to the `util/gh-pages/index.html` and open the html file. Make sure that it can load the lint data. (Browsers can be a bit iffy when opening a loacl html page and loading data)

### Note
I found that searching only a few characters (< 3) seams slow and deleting one even more as almost every lint description contains them. This also happens in our current [lint list](https://rust-lang.github.io/rust-clippy/master/index.html). We could change the search to only be triggered if the search field contains more than 3 letters to slightly improve performance.

9f9e9f7e52 Auto merge of #6316 - ThibsG:WrongSelfConventionTraitDef, r=ebroto
Lint also in trait def for `wrong_self_convention`

Extends `wrong_self_convention` to lint also in trait definition.

By the way, I think the `wrong_pub_self_convention` [example](dd826b4626/clippy_lints/src/methods/mod.rs (L197)) is misleading.
On [playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=32615ab3f6009e7e42cc3754be0ca17f), it fires `wrong_self_convention`, so the example (or the lint maybe?) needs to be reworked.
The difference with `wrong_self_convention` [example](dd826b4626/clippy_lints/src/methods/mod.rs (L172)) is mainly the `pub` keyword on the method `as_str`, but the lint doesn't use the function visibility as condition to choose which lint to fire (in fact it uses the visibility of the impl item).

fixes: #6307

Fix blessing of new reference files

Adding of new reference files wasn't handled correctly. It was trying to
read a file that didn't exist yet.

Instead of unwrapping, we now treat a missing reference file as empty
(`Vec::new`). This makes the following conditional work. We then also
have to re-read the reference file after it was being copied. This
second read is technically the same as in the old shell script, but
wasn't really obvious there. The shell script did a `-s` test which
reads the file as well.

needless_doctest_main: handle correctly parse errors

Before this change, finding an error when parsing a doctest would make Clippy exit without emitting an error. Now we properly catch a fatal error and ignore it.

Also, if a doctest specifies an edition in the info line, it will be used when parsing it.

This essentially changes `ty::Binder<&'tcx List<ExistentialTraitRef>>` to `&'tcx List<ty::Binder<ExistentialTraitRef>>`.

286e492343 Rollup merge of #79051 - LeSeulArtichaut:if-let-guard, r=matthewjasper
Implement if-let match guards

Implements rust-lang/rfcs#2294 (tracking issue: #51114).

I probably should do a few more things before this can be merged:
- [x] Add tests (added basic tests, more advanced tests could be done in the future?)
- [x] Add lint for exhaustive if-let guard (comparable to normal if-let statements)
- [x] Fix clippy

However since this is a nightly feature maybe it's fine to land this and do those steps in follow-up PRs.

Thanks a lot `@matthewjasper` ❤️ for helping me with lowering to MIR! Would you be interested in reviewing this?
