Jonathan Desrosiers bf17761e70 Build/Test Tools: Make adjustments to how often old branches are tested.
This adjusts the workflow responsible for testing old branches to only test old branches once per month. This more closely resembles the testing practices previously in place on TravisCI.

The latest, supported branch will continue to be tested twice per month.

This also makes adjustments so that the workflow is run whenever changes are made to it. This will help verify changes without having to wait until the next scheduled run.

Fixes #52653.
