Pre-commit failed tests

Hello,

I’m trying to add a simple change to documentation related to issue #16624. I’m just trying to removed the three paragraphs about affiliated packages in astropy/docs/development/codeguide.rst and replace them with a link to the affiliated packages information on the astropy website.

I keep running into check-case-conflict and check-merge-conflict (trace below) in Git when I attempt to commit my changes and I am, admittedly, super green, so I’m not sure how to go about solving this. Can anyone lend a hand?
