Pre-sort map keys inside list items in _tests.yaml fixtures

[vinckama]

What does this PR do?

Pre-sort map keys inside list-item maps in _tests.yaml pipeline test fixtures, to avoid a spurious diff when the upstream change lands.

MapHelper.deepSort currently sorts map keys recursively at all depths but stops when it encounters a list — maps nested inside list items are left unsorted. A pending change (logs-backend#138681) extends deepSort to also recurse into lists, so maps inside list items will have their keys sorted the next time fixtures are regenerated.

This PR proactively applies that same ordering so the regeneration produces no diff.
