Fix 5.43 upgrade signoff

[bzarboni1]

Resolves #I2077

---

Before the change?

• For a repository update, there's a bug in the GitHub 2022-11-28 version, that throws a 422 error whenever the web_commit_signoff_required is set to true, even when it is already true.

After the change?

• On a repository update, we check if the web_commit_signoff_required has been modified. If it has, it is passed along in the request. If it hasn't, it is silently dropped from the request.

Pull request checklist

• Tests for the changes have been added (for bug fixes / features)
• Docs have been reviewed and added / updated if needed (for bug fixes / features)

Does this introduce a breaking change?

Apologies for the late reply.
I've tried it here on my end, and had a colleague try as well. The test are successful for us.
