Comment:

 This week the first scheduled run of this workflow occurred:
 https://github.com/WordPress/wordpress-develop/actions/runs/707069966.

 Branches 3.7, and 4.9-5.7 all were tested successfully (the other branches
 did not have the required changes to be run). Here are some notes.

 The workflow was scheduled for the first of the month at 00:00 UTC. When
 jobs are scheduled, GitHub takes all of the jobs with the same scheduled
 time and places them in a pool and they are run as resources are
 available. This resulted in the workflow ''actually'' starting at ~02:34.
 This delay is not a huge deal, but it's worth noting it's not always
 immediate.

 The next scheduled run is on the 15th at 00:00 UTC. After that occurs, I
 think that [attachment:"52653.diff"] should be committed to do a few
 things.

 First, it splits the two scheduled dates into two separate crons. This
 allows us to detect which day it is (1st or 15th).

 Second, it introduces a conditional statement using the separate crons
 above to only test the two most recent branches twice per month, and all
 other branches once per month. This more closely matches our testing setup
 on Travis, and prevents some needless testing.

 And finally, because an overwhelming number of projects are most likely
 running workflows at 00:00 on the 1st, it changes all branches to being
 tested on the 15th, and only the 2 most recent on the 1st.
