Use git.HOME_PATH for Git HOME directory (#20114) (#20293)

Browse source 
Before, in #19732, the old home directory is not correct.
This PR introduces a new config option for git home: git.HOME_PATH,
which is default to %(APP_DATA_PATH)/home

And pass env GNUPGHOME to git command, force Gitea to use a stable GNUPGHOME directory
