Update release notes config and add CI check

After going and adding labels for all of these I found out that 'improvement' should be 'enhancement' and 'bugfix' should be 'bug'
but I don't know how to bulk update them (and I can't rename because the desired labels already exist).

I'll work that out later, this is good enough for now
