ci: Fix broken CI for ASWF 2021 and 2022 containers

The background here takes some explaining...

The ASWF's prepared Docker containers that reproduce a CentOS7-based
environment corresponding to VFX Platform 2021 and 2022 years contain
a glibc that is too old to run a newer version of "node" -- which
GitHub Actions themselves use. The old one is no longer receiving
support, and GitHub finally changed the policy that was allowing its
GHA runners to still run the old version that worked with those ASWF
containers.  The new node version that is happy on the GHA runners
requires a glibc newer than the one in the containers. So that breaks
all our CI runs in 2021 and 2022 VFX Platform configurations.

See this thread, if you dare:
https://academysoftwarefdn.slack.com/archives/C0169RX7MMK/p1732574400981949

Anyway, Jean-Francois Panisset proposed and tested a fix, which lets
us continue working (for now) by downloading an old node implemenation
(which is happy with the old glibc) and installing it atop the
conainers, so it's this old one that the GH actions will use. It feels
like it's all held together by chewing gum and duct tape, but it
unbreaks our CI and hopefully it will keep working until all the
studios have switched fully to RHEL/Alma/Rocky 9.x and we no longer
care about testing on CentOS-7 based containers or supporting the VFX
Platform years that are too old to be relevant to the new OS that the
studios are using.
