DOC-3520: Downgrade Node to 22 LTS in deploy workflow (#4158)

Node 24.16.0 (shipped in runner image 20260525.161.1) causes
isomorphic-git's HTTP transport to silently fail, resulting in
Antora producing zero output. Node 22 LTS is unaffected.

Also reverts the unnecessary Antora version pin from #4155 since
the root cause was Node, not the Antora version.
