archunit-junit5-api's @ArchTag is not composable

[daniel-shuy]

Unlike JUnit 5's @Tag, archunit-junit5-api's @ArchTag is not composable, eg.

@Inherited
@Documented
@Retention(RUNTIME)
@Target( {TYPE, METHOD, FIELD})
@ArchTag("my-tag")
public @interface MyAnnotation {
}

Would appreciate it if archunit-junit5-api could be enhanced to not only check for @ArchTag, but any annotation that composes it.

I guess it makes sense to be close to JUnit Jupiter considering the feature set, so if anybody wants to contribute this, I'd be happy to merge it! (I don't think it should be horribly complicated)
Otherwise I'll try to do it myself, but unfortunately my queue has a ton of other issues to fix before ☹️
