docs: Fix latex formatting, and ignore file

[lsetiawan]

This PR fixes the issue with pre-commit reformating _{ to *{ causing the rendering to not work properly as mentioned in #290 (comment)

For clarity, if something like this occurs in the future the fix is to add the file to the "exclude" list in .pre-commit-config.yaml? I'd like to be able to resolve this myself if it happens again.
