git commands with an sso origin fail with Error: invalid argument: 'port'; class=Invalid (3)

Description

I have an sso url as a git origin: sso://some-org/some-project. running any jj git command fails with Error: invalid argument: 'port'; class=Invalid (3). jj git fetch, jj git push -b my-branch, etc. It even fails to clone; jj git clone <sso url> fails with the same error.

In practice, I'm attempting to use jj in a google internal gerrit instance.

Steps to Reproduce the Problem

run jj git clone sso://anything which will fail before it attempts to make the api call. I don't think you actually need a sso repository setup, but if a googler looks at this ticket I can provide them my internal gerrit instance url to test it on.

Expected Behavior

it clones the repo

Actual Behavior

it fails with invalid argument port

Specifications

• Platform: linux
• Version: 0.17.1

(I also work for Google.)

URLs of the form sso://... (or anything that is not what you'd expect to be generally supported) work in the Git CLI due to an extension mechanism called remote helpers (https://git-scm.com/docs/gitremote-helpers), but the Git library that jj uses to fetch, libgit2, does not seem to support those. You can reach out internally if you want to discuss options.

In principle, we could consider shelling out to git push from jj git push to do the actual pushing, similarly to #2920. This would solve other incompatibilities as well. It would be annoying to maintain, though.
