Add new lint for byte char slices
This patch adds a new lint that checks for potentially harder to read byte char slices: `&[b'a', b'b']` and suggests to replace them with the easier to read `b"ab"` form.

Add new lint `hashset_insert_after_contains`
This PR closes https://github.com/rust-lang/rust-clippy/issues/11103.
This is my first PR creating a new lint (and the second attempt of creating this PR, the first one I was not able to continue because of personal reasons). Thanks for the patience :)
The idea of the lint is to find insert in hashmanps inside if staments that are checking if the hashmap contains the same value that is being inserted. This is not necessary since you could simply call the insert and check for the bool returned if you still need the if statement.

Honor `avoid-breaking-exported-api` in `needless_pass_by_ref_mut`
Until now, the lint only emitted a warning, when breaking public API. Now it doesn't lint at all when the config value is not set to `false`, bringing it in line with the other lints using this config value.
Also ensures that this config value is documented in the lint.

(I don't think a changelog is necessary, since this lint is in `nursery`)

Fixes https://github.com/rust-lang/rust-clippy/issues/11374
cc `@GuillaumeGomez`
Marking as draft: Does this lint even break public API? If I change a function signature from `fn foo(x: &mut T)` to `fn foo(x: &T)`, I can still call it with `foo(&mut x)`. The only "breaking" thing is that the `clippy::unnecessary_mut_passed` lint will complain that `&mut` at the callsite is not necessary, possibly trickling down to the crate user having to remote a `mut` from a variable. [Playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=058165a7663902e84af1d23e35c10d66).
Are there examples where this actually breaks public API, that I'm missing?

Fix#12964 - false positive with `into_iter_without_iter`
changelog: FP: `into_iter_without_iter`: No longer lints when the `iter` or `iter_mut` implementation is not within the first `impl` block
fixes#12964
---
I'm pretty new to this open-source thing, so hopefully I did everything right. Got a little annoyed this false positive was happening in my code and the issue was inactive for two weeks so I thought I'd fix it myself.
As an aside, maybe `iter.map(...).next()` could be linted against? I don't see that ever being preferred over `iter.next().map(...)`, and it could've prevented the bug here.
Don't lint `assertions_on_constants` on any const assertions

`manual_inspect`: fix `clippy::version` from 1.78.0 to 1.81.0
Although `manual_inspect`'s PR started some months ago, the lint is only available in the current nightly (1.81.0), rather than 1.78.0.

doc_lazy_continuation: blank comment line for gap
This change addresses cases where doc comments are separated by blank lines, comments, or non-doc-comment attributes, like this:
```rust
/// - first line
// not part of doc comment
/// second line
```
Before this commit, Clippy gave a pedantically-correct warning about how you needed to indent the second line. This is unlikely to be what the user intends, and has been described as a "false positive." Since Clippy is warning you about a highly unintuitive behavior [that Rustdoc actually has](https://notriddle.com/rustdoc-html-demo-11/lazy-continuation-bad/test_dingus_2024/constant.D.html), we definitely want it to output *something*, but the suggestion to indent was poor.

Fix doc_markdown DevOps false positive
This fixes an issue where the word "DevOps" ends up as a false positive for the `doc_markdown` lint.
In a doc comment like this
```rust
/// Call the Azure DevOps REST API.
pub fn example() {}
```
the word "DevOps" is highlighted as something which should be in backticks.
```
warning: item in documentation is missing backticks
--> src/lib.rs:1:20
|
1 | /// Call the Azure DevOps REST API.
| ^^^^^^

= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#doc_markdown

warning: `example` (lib) generated 1 warning (run `cargo clippy --fix --lib -p example` to apply 1 suggestion)
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.00s
```
This could be overriden with the `doc-valid-idents` configuration parameter as noted by the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#/doc_markdown), but I believe the word "DevOps" is sufficiently common to belong alongside exceptions like "GitHub" and "GitLab".
