Fix all occurences `needless_borrow` internally
The bug that got 'needless_borrow' moved into the nursery was fixed two years ago in d4370f8b.
This did trigger over a thousand times internally, so that's all the other changes. I vetted most of them, but there's a lot The only interesting change is to the lint list. `declare_tool_lint` already makes a reference, so there's no need to take a reference to the lints.

consider mutability on useless_vec suggestions
fixes#7035
changelog: Now the suggested by `useless_vec` considers mutability to suggest either `&[]`, as before, or `&mut []` if the used reference is mutable.
This is a quick-fix for an ICE in `tabs_in_doc_comments`. The problem
was that we we're indexing into possibly multi-byte characters, such as '位'.
More specifically `get_chunks_of_tabs` was returning indices into
multi-byte characters. Those were passed on to a `Span` creation that
then caused the ICE.
This fix makes sure that we don't return indices that point inside a
multi-byte character. *However*, we are still iterating over unicode
codepoints, not grapheme clusters. So a seemingly single character like y̆ ,
which actually consists of two codepoints, will probably still cause
incorrect spans in the output.

New Lint: `branches_sharing_code`
This lint checks if all `if`-blocks contain some statements that are the same and can be moved out of the blocks to prevent code duplication. Here is an example:
```rust
let _ = if ... {
println!("Start"); // <-- Lint for code duplication
let _a = 99;
println!("End"); // <-- Lint for code duplication
false
} else {
println!("Start");
let _b = 17;
println!("End");
false
};
```
This could be written as:
```rust
println!("Start");
let _ = if ... {
let _a = 99;
false
} else {
let _b = 17;
false
};
println!("End");
```
---
This lint will get masked by the `IF_SAME_THEN_ELSE` lint. I think it makes more sense to only emit one lint per if block. This means that the folloing example:
```rust
if ... {
let _a = 17;
} else {
let _a = 17;
}
```
Will only trigger the `IF_SAME_THEN_ELSE` lint and not the `SHARED_CODE_IN_IF_BLOCKS` lint.

Remove author requirement for `cargo_common_metadata`
This PR follows https://github.com/rust-lang/cargo/pull/9282, I'm not fully informed about all of this, it would be great if somebody knowledgeable about this topic agrees.
changelog: Changed `cargo_common_metadata` to stop linting on the optional author field.
* Added expression check for shared_code_in_if_blocks
* Finishing touches for the shared_code_in_if_blocks lint
* Applying PR suggestions
* Update lints yay
* Moved test into subfolder
Quick fix for the updated website theaming to access the correct css files
This fixes a problem from #7030 that the service used to access css files was blocked by GitHub pages due to `SSL_ERROR_BAD_CERT_DOMAIN`. The css file loading worked fine during local development. The browser probably disabled some security options due to the local address.
This fix works locally and should also work online as it references the direct css files used by the [mdBook User Guide](https://rust-lang.github.io/mdBook/index.html) the disadvantage of this is that refactorings within the mdBook project can have effects on the theme loading of Clippy. This PR is therefor more meant as a quick fix until I find a better solution.
I've tested these changes using the page editor in the browser and can now confirm that they work :)
