#[IgnoreDeprecations] is not being identified as a marker of deprecated scope

[mondrake]

PHPUnit 10.5 introduced a new #[IgnoreDeprecations] attribute sebastianbergmann/phpunit#5532 to signal that a test is exercising deprecated code paths i.e. that calls to deprecated methods/functions are expected.

PHPStan however is reporting calls to deprecated functions in that test as errors.

Recently, a similar issue was reported for Symfony's PHPUnit-bridge definition of @group legacy annotated tests, #64

As this project provides a DeprecatedScopeResolver as an extension point, this is something that belongs to https://github.com/phpstan/phpstan-phpunit to implement such a resolver aware of the phpunit attribute
