Test Plan:

Instead of just supporting pem001 (3 letters and 3 numbers) we need to support org-name (at least 1 letter, dash and at least 1 letter) as well.

Copied test script from #13113

Regex changes look good; unit tests cover the previous and added functionality. Nice job with the postinstall-test.sh script 😄
