update node version in container build actions

[johnsonshih]

What this PR does / why we need it:
Recently we started to hit errors when building application containers, the error is due to the version of node.js (12) is too old, update to version 18 to get rid of the errors.

Special notes for your reviewer:
There is another issue that Build Anomaly Detection App Container / per-arch (arm32v7) job takes forever to complete. I'll address that in a separate PR.
