Fix Generic materialization for type aliases

[pomadchin]

The same as #1249 but against the main branch.

Closes #1248

The issue is here: https://github.com/milessabin/shapeless/blob/main/core/src/main/scala/shapeless/generic.scala#L880 - tpe.typeArgs is different for the type alias and doesn't match apply - this fix does the job. If we remove the typeArgs another test fails. Unfortunately that also means that custom apply methods with a different number of type arguments won't work. I will think a bit more about it but this fix is probably the best we can do.

I can't think of a better solution. Thanks for the fix 👍
