Add `ui_cargo_toml_metadata` test
This PR adds a test to check the metadata of packages in the `ui_cargo` directory.
A recent change to Cargo causes it to warn when it finds multiple packages with the same name in a git dependency (the issue is described [here](https://github.com/rust-lang/cargo/issues/10752)).
Many (if not all) Dylint libraries depend upon `clippy_utils`. As a result of the change, one now sees the following when building a Dylint library:
```

```
There appear to be two contributing factors:
- Some packages in `ui_cargo` could have a `publish = false` added to them.
- Some packages in `ui_cargo` seem to be inconsistently named.
The new test checks that each package in the `ui_cargo` directory has a name matching one of its parent directories, and `publish = false` in its metadata (with a few exceptions).
Note that the packages in `cargo_common_metadata` require special care because `publish` is the subject of some of the `cargo_common_metadata` tests.
Also note that this PR adds `walkdir` as a dev dependency to the `clippy` package. However, it was already a dependency of `clippy_dev` and `lintcheck`. So hopefully this is acceptable.
Our continued thanks for making `clippy_utils` available, BTW. :)

Fix typo in alloc_instead_of_core
The description previously claimed it ensures items are imported from alloc, to ensure a crate won't require alloc, which can't be true.
I'm not sure know how to better phrase the changelog entry below.

Add new lint `obfuscated_if_else`
part of #9100, additional commits could make it work with `then` and `unwrap_or_else` as well

Fixes#9195.
I mostly copied the implementation from `unnecessary_wraps`, since I don't have much understanding of rustc internals.
Update highlight.js
changelog: none
With [highlight.js v11.6.0](https://github.com/highlightjs/highlight.js/releases/tag/11.6.0), the lint list can finally update from `9.5.0`. No more EOL warning in console! 😄
I also made it switch to the `github-dark` theme when using `coal`, instead of just always using the normal github light theme.
r? `@xFrednet`
Add `std_instead_of_core`, `std_instead_of_alloc`, `alloc_instead_of_core`
Closes#7724
Introduces 3 new lints:
- `std_instead_of_core` - lints items resolved through `std` which are available in `core`
- `std_instead_of_alloc` - lints items resolved through `std` which are available in `alloc`
- `alloc_instead_of_core` - lints items resolved through `alloc` which are available in `core`
Though the original issue only mentions `std_instead_of_alloc`, the other two lints could be useful as well.
questions:
- what do I call the file the lints live in? I was thinking `std_reexports`?
changelog: new lint's: [`std_instead_of_core`], [`std_instead_of_alloc`], [`alloc_instead_of_core`]
[`box_collection`]: raise warn for all std collections
So far, only [`Vec`, `String`, `HashMap`] were considered.
Extend collection checklist for this lint with:
- `HashSet`
- `VecDeque`
- `LinkedList`
- `BTreeMap`
- `BTreeSet`
- `BinaryHeap`

Move format_push_string to restriction
Fixes#9077 (kinda) by moving the lint to the restriction group. As I noted in that issue, I think the suggested change is too much and as the OP of the issue points out, the ramifications of the change are not necessarily easily understood. As such I don't think the lint should be enabled by default.
