Switch to Gitlab CI

Happy to follow up on that, probably over the next couple of days (weekend my time).

Based on the docs and so on, I don't quite get yet how you'd then set up something similar to https://www.drupal.org/node/17345/qa. I don't need all the variations, but what I think would be nice is a weekly run on PHP 8.2 and PostgreSQL additionally to the default. I guess that's where scheduling and custom variables come into play.

Great, let's do that!

1. Visit https://git.drupalcode.org/project/pathauto/-/pipeline_schedules once this MR is landed
2. Click "New schedule"
3. Set the schedule to "Every week" (or use crontab format - but I think Gitlab may be helpful here with its timing recommendation ... IDK)
4. Refer to https://git.drupalcode.org/project/gitlab_templates/-/blob/1.0.x/include... for variable definitions and names for the following
5. Set a variable named _TARGET_PHP to $CORE_PHP_MAX (or literal 8.2 if you prefer to specify).
6. Press save, and then click the ▶️ start button on that schedule to fire a test run
7. A pipeline will start; you can click into that pipeline and inspect the version of PHP from the "composer" job; it appears at the top of the output, eg Using Kubernetes executor with image drupalci/php-8.2-apache:production ... on line 7 shows we're using PHP 8.2 here (ref example pipeline, job)

Thanks @greggles!

I've removed from #8 the notes on trying to get this set up for a Postgres run as well. I did get that working in the end:

Scheduled pipeline for testing with Postgres

For a weekly Postgres test run, repeat instructions from #8 above, changing step 5 to assign two variables below.

1. _TARGET_DB_TYPE = $POSTGRESQL
2. _TARGET_DB_VERSION = 14.1

To confirm which DB service starts, we'll then inspect the "phpunit" job and check which image is pulled for the DB service at job start.

At first I thought it should be possible to use a variable such as $CORE_PGSQL_MAX for _TARGET_DB_VERSION, but those values weren't matching the images over on Docker Hub (eg 14.1 to use drupalci/pgsql-14.1). So I switched to static values (eg "14.1") and that worked. There may be a better way to configure this for "test on the latest available postgres", but this worked for me. (Update: Per #3390706: PHP and Database available versions should match the supported versions, I wasn't alone in drawing that expectation.)

I also ran into some issues pulling Docker images, which was I think in part rate limiting of image pulls from Docker hub ((thread in Slack #gitlab) as well as me coming up with incorrect image names on some tries due to the expectation in previous paragraph. :)

Example pipelines

I tested this on AdvancedForm module (something with few tests I had sufficient access to experiment with). Here are example pipelines for that project on Postgres 14.1 (_TARGET_DB_TYPE=$POSTGRESQL, _TARGET_DB_VERSION=14.1), MySQL 8 (_TARGET_DB_TYPE=$MYSQL_PERCONA_MARIADB, _TARGET_DB_VERSION=8), and PHP 8.2 (_TARGET_PHP=$CORE_PHP_MAX).

Correction to above: I *did* get that configuration working. Laptop battery had me hit save without reviewing my comment.

Needs review now :)

Thanks!
