docs: add Centos/RHEL9+, thanks for nothing RedHat

[janl]

we can merge this after we publish the rocky9 build rpm

[nickva]

Due to the generous support from IBM's Z open source support team (@kun-lu20) in apache/couchdb-ci#54 we have RHEL9 (clone) support with the caveat that it depends on the EPEL repo.

I just uploaded the x86-64 3.3.2 centos-9 rpm to our artifactory

yum install couchdb

Complete!

[nickva]

For me on Almalinux 9 VM adding epel-next-release wasn't needed. I used just epel-release

[janl]

Good catch! That’s why I specifically pulled out RedHat >=9 from RedHat/CentOS <=9) — I hope that helps. IF we get reports that the “next” bit is wrong, we can adjust on the fly.

[nickva]

Ah good point. It's a RHEL 9 only instructions. Most people would probably figure the Almalinux / Rocky 9 instructions. If we got a lot questions we can add them later.

[nickva]

+1

Package created, signed and was uploaded. See a minor comment about epel-next. I tried it on AlmaLinux 9 not sure if it's a Rocky vs Centos9 vs Alma thing or something else.

thanks for nothing RedHat

Heh ;-) Tbh, I think this is just as much a "Thanks for nothing, Mozilla". I can't blame Redhat not wanting to support Spidermonkey 78 for 15 years. I wouldn't either.

We have the same problem as Redhat as SM keeps changing their "stable" API with every release (see #4305) That stuff works for a browser, but is not tenable for an "embedded" engine.

"Thanks for nothing, Mozilla"

totes fair :) This is just happening at the same time as RedHat is trying to take the RHEL sources private, which creates uncertainty and potentially more work for us for no good reason :)
