Ignore deprecation of AnnotationsRegistry

[danepowell]

ORCA scans for deprecated function calls by default.

BLT uses ORCA as well as the AnnotationsRegistry from doctrine/annotations. Unfortunately, AnnotationsRegistry was deprecated even though no alternative currently exists (an alternative will come in the next major release). I consider this a bug in the annotations library, but the maintainer hasn't expressed willingness to fix the situation: doctrine/annotations#270

In order to get deprecation tests running again, I think the best solution would be for ORCA to add a phpstan ignoreErrors directive to ignore the following deprecation error until the upstream bug with doctrine/annotations is fixed:
Call to deprecated method registerFile() of class Doctrine\Common\Annotations\AnnotationRegistry.

If there were any way to solve this within BLT without involving ORCA I definitely would, but it looks like the only way phstan can ignore false positives is via global configuration: phpstan/phpstan#786

Fixed, @danepowell. Thank you. You can patch ORCA while you're waiting for the next release if you like:
