This contained quite a lot of outdated information and steps
that were duplicated with the SOPs. This revises it to focus
on a full release cycle workflow, mainly linking out to the
release step SOPs, with a few remaining notes that don't fit
anywhere else kept at the bottom.
Note this entirely drops the notification of release-blocking
deliverables for a release - it was only done for F31 and F32,
and nobody seems to be missing it.
This also removes some duplication between the No-Go SOP and
the Release Delay SOP and has a few other small updates and
cleanups.
