docs: remove default_branch from config.yaml

[jackhodgkiss]

By setting the default_branch the generation of release notes fails to capture all of the tags releases within a given branch.

This was required to get zuul CI to work #1791

Do you know any other way we could get this to work?

What is Zuul doing that means the configuration for release notes requires default branch set?

It runs a pep8 job which isn't really pep8, it's more just a release notes check. For some reason it succeeds in GH CI but fails in zuul https://zuul.stackhpc.com/t/stackhpc/build/54c03714f1f2432ea7db98c1900e641b

It is because the repository is cloned with --bare this causes the error ValueError: Unknown reference 'master'

The docs for reno say that --branch can be provided however this doesn't work for reno lint. In fact --branch appears on all but reno lint. https://static.opendev.org/docs/reno/2.3.0/usage.html#configuring-reno

Can we skip this part of the Zuul job?
