[Feature Suggestion] Avoid git ownership problems with portable version

[eumelzocker]

When using the portable version on my second computer, git complains about dubious ownership in all repositories.

Example:

fatal: detected dubious ownership in repository at 'D:/ai/StabilityMatrix/Data/Packages/stable-diffusion-webui'
...

I fixed the problem by adding a section to /path/to/StabilityMatrix/Data/PortableGit/etc/gitconfig

[safe]
	directory = *

This makes the portable version really portable. I think that should be added by default.
