only can override hotkeys with the installed abapGit repo.

* New: Override hotkeys within one file abapGit report
When this commit is applied it's possible to override the default
shortcut also in the one file abapGit report. It's no longer necessary

* Extract is_merged + check in hotkey logic
With this commit we are able to define global hotkeys. Which means
that the hotkey is active on all pages. The global hotkeys are
defined in ZCL_ABAPGIT_GUI_PAGE=>GET_HOTKEY_ACTIONS. The first
globally defined hotkey is the hotkey overview with the default
hotkey '?' assigned to it. This was previously hard coded in the js.
