Gitea Actions run actions as JavaScript via `node` inside the
job container. The maven:3.9.6-eclipse-temurin-21 image has no
node, so action post steps (e.g. Checkout cleanup) fail with
'exec: "node": executable file not found in $PATH'.
Extend the install step to add git AND node 22 via NodeSource
apt repo, so the runner can complete every action's pre/post step.
