I think the website could use some better guidance on this. That page has a
lot of keys for a lot of people. Are they all trusted to sign FreeBSD
releases?

Assuming that they're not, it would be great if the signatures page were
updated to include a list of keys that are expected to sign a release.
https://www.freebsd.org/releases/13.0R/signatures/

I say this because I had problems finding this as well when writing our
deployment automation. It's the reason why I did not automate grabbing
new releases and verifying them, and still leave that as a manual human
step.
