Specify the branch to use when starting a workspace from an SSH Git URL

[svor]

Is your task related to a problem? Please describe

When using an HTTPS Git URL, it's possible to specify a branch directly in the URL. SSH, however, does not support this — it only allows referencing the remote repository.
We need to investigate how a specific branch can be selected when using the SSH flow.

Describe the solution you'd like

Maybe we can add query parameter support for branch specification:

HTTPS: https://github.com/user/repo?branch=feature-branch
SSH: git@github.com:user/repo.git?branch=/feature/nice-feature

I believe we should include the fix in 7.109.0 release for 3.24.0
