Improve descriptions of key-mappings in neovim and align git-shortcuts

I struggle to remember certain shortcuts sometimes. In these cases I
rely on the "whichkey" plugin which shows a short description of for
each possible keystroke in vim. Though I was lazy and didn't maintain
these everywhere, so this change fixes that. Hopefully I can remeber all
the keys better now.

Furthermore this change contains some slight remappings regarding the
git-keymappings. I used fugitive for most of that in the past, but I saw
more potential using telescope in certain cases, especially navigating
the history.
