The git-modes package replaces gitconfig-mode and gitignore-mode (and gitattributes-mode)

[tarsius]

I have released Git-Modes on NonGNU Elpa as well as on Melpa. Git-Modes provides three simple major modes for editing Git configuration files.

Previously these modes were available from Melpa as three separate packages named gitattributes-mode, gitconfig-mode and gitignore-mode. These packages have been removed and you should remove them locally too and then install git-modes, but make sure that it is already available before you do. That can take a few hours.

The announcement: https://emacsair.me/2021/10/21/git-modes/.

Expected behavior

Use the package git-modes.

Actual behavior

Prelude still tries to use the packages gitconfig-mode and gitignore-mode, which no longer exist.

Steps to reproduce the problem

Try to install git-modes and be told there is no such package.
