docker/root/usr/bin/entrypoint already allows for the specification
of USER, USER_UID, USER_GID. But since AllowedUsers is hardcoded in
sshd_config, one cannot log in as a user different ftom git.
This change substitutes ${USER} for git in the sshd_config template.

* - rearrange the templates to make it more logical because now ssh_config is a template
- implemented the updating of the port to the same as the port sent to the gitea config
* change the filename back
