else building fails for me on Fedora 34 with:

$ ./build.sh 
This build script is using Podman to run the build in an isolated environment.
[12:05:19.194] FATAL (antora): configuration param 'runtime.pull' not declared in the schema for /antora/site.yml (cwd: /antora, playbook: site.yml)
Add the --stacktrace option to see the cause of the error.

Hm. There are a lot of unrelated changes in this PR (including some that look like no-ops).

It builds for me on F35 and, since F34 is about 5–6 weeks from going EOL, I'm wary about pulling in fixes for it. It seems to not break on F35, though, so I'll go ahead and merge it.

Nevermind, Pagure won't let me:

Your task failed: 'object not found - no match for id (e92d092e67b2ed4e0c7804ad93928a2dfd83da10)'

Probably better to split this into two separate PRs anyway, in order to keep them focused on one change.
