[v3,4/5] ref-manual/system-requirements.rst: fix AlmaLinux PDF build

Use the new tlmgr_docs_pdf.sh script in build-docs-container to fix
the build of the documentation PDF for AlmaLinux 8 and 9.

Fix the almalinux_essential.sh script to either enable powertools or crb
depending on the AlmaLinux version (powertools for 8, crb for 9).

Containerfile.stream is a symlink to Containerfile.dnf I believe so... why?

Looks ok to me otherwise,
