Add support for a "nightly" alias

[williamdes]

Describe the bug

I had to comment out the next PHP 8.2 version as it does not exist yet for this action.
See: phpmyadmin/sql-parser@dd2f634

TravisCI (sorry to mention it, I would prefer that we forget about it) had support for "nightly" in the php version matrix. This was helpfull

Are you willing to submit a PR?
Sorry, I am missing time

Ah, form mistake, not a bug

@williamdes
8.2 should work and set up 8.2.0-dev from the master branch of php. I added builds last week. The docs will be updated in the next release.

In Travis, IMHO this was broken as they won't update the nightly as it would shift to the next to next version (8.2) and you would not be testing the next version (8.1) in your workflow until support is added for it and you add it to your workflow.

Instead of a nightly tag, I would rather prefer that for testing master, projects add the version in master (8.2) in the workflow. But if you prefer a nightly tag I will add it in the next release.
