Fixes problem with using deprecated node.js

[butlerpd]

Description

Our builds are throwing a number of warnings every time a CI runs due to the deprecated version of the node.js module being used by the older versions of actions/setup-python and actions/checkout. The latest version are using the upgraded node.js

Note: that line 38 of nightly-build.yml was using actions/setup-python@v1 instead of v4. It was also incremented to v5 but we should pay attention here - though it will likely have no affect until merged to main?

Fixes #2810

How Has This Been Tested?

TBA (needs to build)

Nightly build should only be called from main branch, so we probably will need to the same fixes to main

There are still node.js warnings in this build related to actions/upload-artifact@v3 and actions/download-artifact@v3. These should probably be changed here.

There are still node.js warnings in this build related to actions/upload-artifact@v3 and actions/download-artifact@v3. These should probably be changed here.

Both should be upgraded to v4

@butlerpd I forgot about this PR and started working #2860... Can we merge this one and then merge #2860?

[krzywon]

#2860 fixes the other build warnings, so I'm merging this so the other PR isn't held up.
