Require phpstan ^2.2 and drop the two stale implode baseline entries

The PhpStan check in .laminas-ci.json runs on latest dependencies, so it
picks up phpstan 2.2, which no longer reports the two implode
argument.type errors in Metadata\Source. The baseline still ignored them,
so the job failed on ignore.unmatched, which is non-ignorable.

2.1 does still report them, so the entries cannot simply be removed while
the lock stays on 2.1; require-dev moves to ^2.2 so both the locked and
latest jobs analyse with a version that agrees. Pre-existing on 0.1.x, and
unrelated to getQueryResult, but it fails this PR's CI.
