Enable Wire 2 for Internal SSH Server (#20616)

- Git only decides to use the Wire 2 protocol when `git
{receive,upload}-pack` receive the `GIT_PROTOCOL` environment with as
value `version=2`. Currently the internal SSH Server wasn't passing this
environment through. The `gitea serv` code already passed all received
environments to the git command, so no code changes there.
