Subject: [PATCH] Fix missing highlight for macro_invocation bang (#41572)

(Not sure if this was left out on purpose, but this makes things feel a
bit more consistent since [VS Code parses bang mark as part of the macro
name](https://github.com/microsoft/vscode/blob/main/extensions/rust/syntaxes/rust.tmLanguage.json#L889-L905))


Release Notes:
- Added the missing highlight for the bang mark in macro invocations.
