oh-my-git: init at 0.6.4

Motivation for this change

Add the package for @davidak's package request. Closes #112341. I played about half of the levels and there seem to be no problems running the game.

The godot export commands expects a copy of the godot export templates at $HOME/.local/share/godot/templates/3.2.3.stable/.... First i downloaded the zip archive from https://godotengine.org/download and copied the templates to the expected location. But the version of these export templates and the godot compiler need to be in sync.

Therefore i added godot-export-templates based on the headless/server package. Now the version of godot and the export templates are automatically in sync.

Thanks for creating the packages! ✨

You should add git as runtime dependency. Someone who plays this game to learn git might not have it installed already.

tested with:

[nix-shell:~/.cache/nixpkgs-review/pr-119642]$ nix-shell -p --pure

[nix-shell:~/.cache/nixpkgs-review/pr-119642]$ git
The program 'git' is not in your PATH. It is provided by several packages.
You can make it available in an ephemeral shell by typing one of the following:
  nix-shell -p git
  nix-shell -p git-doc
  nix-shell -p gitMinimal
  nix-shell -p gitSVN

[nix-shell:~/.cache/nixpkgs-review/pr-119642]$ results/oh-my-git/bin/oh-my-git

Change looks otherwise good.

Builds and works. Even finds my previous savegame :)
