Ready to move to RTC mode and produce a pre-3?

[Sidney Markowitz]

We are down to no more open bugs and sufficient success on the CPAN test 
machines. My understanding is that testing of trunk in production environments 
has gone well.

If nobody has anything that they are working on that they intend to commit, or 
any other issues to bring up, I would like to go to RTC mode and I'll then cut a 
pre-release 3 that people can test with. If that passes a short time for testing 
I'll cut a release candidate in preparation for actual release.

I don't think we need a formal vote. Let's use lazy consensus over the next 72 
hours for anyone who has a reason not to switch to RTC to speak up. I'm going to 
call it 22:22:22 UTC Monday 22 Aug 2022 because that's close enough to 72 hours 
and it is kind of a cool time and date.
