ErrorSuppressionTest::testCommenting(): refactor to data provider
* Maintains the exact same existing tests, now using a data provider. The data provider uses keys which allows for much more descriptive output when using the PHPUnit `--testdox` option, as well as for easier debugging if/when a test would fail. * Orders the tests in logical groups in the data provider. * Switches out `assertEquals()` (loose type comparison) for `assertSame()` (strict type comparison). * Caches the `$config` and `$ruleset` for the test via static local variables to prevent the test run from becoming slower due to the change to the data provider.
