Use native gh CLI for actions and workflows

[mogres]

@rugeli do you know if we are still using this gh action? I believe we wanted to move to a native github cli implementation at some point.

yes we’re still using it in make-requirements.yml to open the pr when uv.lock updates.
I agree with moving to native gh cli where possible(we already use it in analyze.yml). For this pr I’d just merge the bump to v8 to keep things compatible, and I can write a ticket to move our workflows to native gh cli later.
