Bump phpstan/phpstan and mglaman/phpstan-drupal to latest

Note: Creating a new PHPStan-baseline exposed some formatting differences between the generated and committed-in-HEAD one.
Let's use this issue to reconcile these.

As a side note: If people are manually editing the baseline, let's make the GitLab job fail on these differences, so we don't need this kind of reconciliation.

Let's bump the minimum version of mglaman/phpstan-drupal here, because it fixes a PHPStan crash over in 📌 Use a tagged service iterator for uninstall validators instead of individual lazy proxies Needs review

Ah crap, of course, forgot that in my "rage" about the baseline formatting.

Thanks!
