Most time, when invoking `git.OpenRepository`, `objectFormat` will not
be used, so it's a waste to invoke commandline to get the object format.
This PR make it a lazy operation, only invoke that when necessary.
(cherry picked from commit e84e5db6de0306d514b1f1a9657931fb7197a188)
The test suite was broken e.g. on Debian 12 due to requiring a very
recent version of Git installed on the system. This commit skips SHA256
tests in the git module, if a Git version older than 2.42 or gogit is used.
Currently only SHA1 repositories are supported by Gitea. This adds
support for alternate SHA256 with the additional aim of easier support
for additional hash types in the future.
