Workflow grid generator missing files

[dsenalik]

1. The generated phpunit files are missing one combination, I suspect because it was excluded from postgres 14

Expected                         Generated
MAIN-phpunit-php8.2_D10_5x.yml   MAIN-phpunit-php8.2_D10_5x.yml

See PR tripal/tripal#2370 for the ALL-phpunit.yml file used here.

2. The 4.x in the generated file should be single quoted

8c8
<       - 4.x
---
>       - '4.x'
