Include git restore and git switch in your guide

[mroavi]

Newer versions of git promote the use of git restore in the help messages in favor of the git checkout command I believe.

git-restore is about restoring files in the working tree from either the index or another commit.

E.g:

> git status
On branch master
Your branch is ahead of 'origin/master' by 124 commits.
  (use "git push" to publish your local commits)

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
	modified:   nvim/.config/nvim/lua/usr/plugins/init.lua

Would be nice if you update the guide with this recent change.

Also, they introduced the switch command, both helping with the overloaded checkout command. These commands were introduced in git 2.23 (Medium.com article). @mroavi maybe add switch to the issue title?
