Do not retest if retest-not-required is applied
Do not retest if retest-not-required is applied

When a PR hasn't been tested in a while, it is retested by the bot.
This behavior also happens when the PR has the label retest-not-required
or retest-not-required-docs-only, because the label is initially meant
for the submit-queue. Let's not retest if it's not required.
