Your Godot version:

Issue description:
Current documentation still refers to using the pre-commit hook found in misc/hooks which doesn't exist anymore as it was changed by: godotengine/godot#88866. More info: godotengine/godot#88901.

URL to the documentation page:
I've only found references here:

• https://docs.godotengine.org/en/latest/contributing/development/code_style_guidelines.html#pre-commit-hook
• https://docs.godotengine.org/en/latest/contributing/development/code_style_guidelines.html#id3
