Less authoritative stable_sort_primitive message

fixes #8241

Hey all - first contribution here so I'm deciding to start with something small.

Updated the linked message to be less authoritative as well as moved the lint grouping from `perf` to `pedantic` as suggested by `@camsteffen` under the issue.

Thank you for making Clippy better!

We're collecting our changelog from pull request descriptions.
If your PR only includes internal changes, you can just write
`changelog: none`. Otherwise, please write a short comment
explaining your change. Also, it's helpful for us that
the lint name is put into brackets `[]` and backticks `` ` ` ``,
e.g. ``[`lint_name`]``.

If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.

If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.

- \[ ] Followed [lint naming conventions][lint_naming]
- \[ ] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[ ] Added lint documentation
- \[x] Run `cargo dev fmt`

[lint_naming]: https://rust-lang.github.io/rfcs/0344-conventions-galore.html#lints

Note that you can skip the above if you are just opening a WIP PR in
order to get feedback.

cbdf17c884 Auto merge of #8707 - OneSignal:await-invalid-types, r=llogiq 
Add `await_holding_invalid_type` lint

changelog: [`await_holding_invalid_type`]

This lint allows users to create a denylist of types which are not allowed to be
held across await points. This is essentially a re-implementation of the
language-level [`must_not_suspend`
lint](https://github.com/rust-lang/rust/issues/83310). That lint has a lot of
work still to be done before it will reach Rust stable, and in the meantime
there are a lot of types which can trip up developers if they are used
improperly.

I originally implemented this specifically for `tracing::span::Entered`, until I discovered #8434 and read the commentary on that PR. Given this implementation is fully user configurable, doesn't tie clippy to any one particular crate, and introduces no additional dependencies, it seems more appropriate.

95de4dcb5e Auto merge of #8701 - xFrednet:0000-clippy-print-hir-attr, r=flip1995 
Rework `#[clippy::dump]` attribute for debugging

Hey `@rust-lang/clippy,` this adds a new `#[clippy::print_hir]` attribute that prints the node to the console using `{:#?}`. Personally, I use print debugging quite a lot while working on Clippy, and this is a simple shortcut that also works in the playground (Once this has been synced). The question is now, if we want to have this attribute. Are there any concerns? I think it's similar to our `#[clippy::author]` attribute.

I haven't added a test, as the `.stdout` file would require updates with every HIR change inside rustc. Here are some examples, for the current implementation

4844325faf Add await_holding_invalid_type lint 
changelog: [`await_holding_invalid_type`]

This lint allows users to create a denylist of types which are not allowed to be
held across await points. This is essentially a re-implementation of the
language-level [`must_not_suspend`
lint](https://github.com/rust-lang/rust/issues/83310). That lint has a lot of
work still to be done before it will reach Rust stable, and in the meantime
there are a lot of types which can trip up developers if they are used
improperly.

Spellcheck

I'm brand new to this so any feedback will be helpful. I set the project up locally and ran a spellcheck on it. The code changes should only be spelling corrections. I ran the build and tests and they came back successful locally.

changelog: Various spelling corrections in comments and code.
