* Add git.HOME_PATH

* add legacy file check

* Apply suggestions from code review

Co-authored-by: zeripath <art27@cantab.net>

* pass env GNUPGHOME to git command, move the existing .gitconfig to new home, make the fix for 1.17rc more clear.

* set git.HOME_PATH for docker images to default HOME

* Revert "set git.HOME_PATH for docker images to default HOME"

This reverts commit f120101ddc267cef74e4f4b92c783d5fc8e275a1.

* force Gitea to use a stable GNUPGHOME directory

* extra check to ensure only process dir or symlink for legacy files

* refactor variable name

* The legacy dir check (for 1.17-rc1) could be removed with 1.18 release, since users should have upgraded from 1.17-rc to 1.17-stable

* Update modules/git/git.go

## Git (`git`)
- `PATH`: **""**: The path of Git executable. If empty, Gitea searches through the PATH environment.
- `HOME_PATH`: **%(APP_DATA_PATH)/home**: The HOME directory for Git.
This directory will be used to contain the `.gitconfig` and possible `.gnupg` directories that Gitea's git calls will use. If you can confirm Gitea is the only application running in this environment, you can set it to the normal home directory for Gitea user.
