[cms-ci][yaml-tests] Upstream tracking - Post multiple comments to GitHub when limit is reached

[ElijahLynn]

I opened this upstream issue for "Post multiple comments to GitHub when limit is reached"
provision-ops/yaml-tests#52

And/or once we enable the "fail_fast" option in yaml-tests, we should consider just posting the tail, most recent log so we have a better chance of getting the full error in the comment.

this may be deprecated based on outcomes of #3303.

linking to Drupal 9 #1950 epic to keep track of.

Let's icebox this until we all regroup and discuss our overall testing architecture in #4109.
