Revert "git: Make the version_control.{deleted/added} colors more accessible" (#43512)

Reverts zed-industries/zed#43475

The colors ended up being too dark. Zed adds an opacity to the
highlights.


https://github.com/zed-industries/zed/blob/2840f37e07f6e32aa85b3dd03b08b5b094841110/crates/editor/src/element.rs#L9195-L9200


Reverting to avoid having the colors go out in preview will fix shortly
after.
