CI should check for properly formatted wgsl

[BenjaminBrienen]

What problem does this solve or what need does it fill?

This is an example of a file which is not formatted properly. It has trailing whitespace.

crates\bevy_ui\src\render\ui.wgsl

What solution would you like?

There should be a step in the CI job which checks that wgsl files are formatted properly.

What alternative(s) have you considered?

None

Additional context

I noticed a random whitespace change in this PR caused by unformatted code being merged.

What tool should we use to do this check?

[mockersf]

wgsl-analyzer has a bin crate to format: wgslfmt https://github.com/wgsl-analyzer/wgsl-analyzer/blob/main/crates/wgslfmt/src/main.rs

see wgsl-analyzer/wgsl-analyzer#67 (comment) for an example in how to install and use it

[BenjaminBrienen]

The problem with that tool is that it isn't meant to be used like cargo fmt. It requires passing in every file name.

Also, the tool seems dead. Pasting my comment from discord:

wgsl-analyzer looks dead. Should we fork it and bring it into the bevyengine org? There are issues that need to be fixed which block #15470/#15449.
If you think it sounds like a good idea, I'm willing to adopt it.
