docs: example aliases for use with git repo

[kylo252]

I literally just learned about -g by pure chance, and really like it!

I figured I could share some simple, yet highly productive, git aliases that
would make it even seamless to make use of dotbare with any git repo.

# git config alias.fgrep 'git fuzzy fgrep'
git fgrep

you even get completion 😁

❯ git fuzzy flog -
[option]
--checkout  -c  -- checkout the selected commit and skip action menu
--edit      -e  -- edit the selected commit and skip action menu
--help      -h  -- show help information
--reset     -R  -- reset the selected commit and skip action menu
--revert    -r  -- revert the selected commit and skip action menu
--yes       -y  -- acknowledge all actions and skip confirmation

@kazhala, I'm not the best when it comes to writing documentation, so feel free to suggest any edits you see fit!
