feat: no update git refs method

[mittal-umang]

Currently there is no update git refs method in Repository.py which leads to commits not being associated to any branch on Github.

this request cannot be executed. https://docs.github.com/en/enterprise-server@2.22/rest/reference/git#update-a-reference

Any chance of getting the pull request reviewed and merged?

I landed on this exact issue when searching Repository class for updating a git ref and couldn't find a method. Then I did a code search for all PATCH apis and found one in GitRef.edit method that does exactly that. So this issue can be closed
