Display a better error message when a folder is moved

[mikemaccana]

Heya! I love Fork, thanks for being awesome! Just a suggestion:

Unexpected error:
open git config at '/Users/mike/Code/quicknode/yellowstone-fromslot/.git/config'
No such file or directory (os error 2)

Please contact Fork support

Nobody needs to contact suppoert for that. The message should be something like

Could not find git config in /Users/mike/Code/quicknode/yellowstone-fromslot. The folder may have been moved or renamed!
