javasrc2cpg: `inheritsFromTypeFullName` should contain type parameters

[fabsx00]

For CustomerRepository in Hello ShiftLeft, I get the following:

 cpg.typeDecl.name("CustomerRepository").isExternal(false).inheritsFromTypeFullName.l
res2: List[String] = List("<unresolved>.CrudRepository")

although the class actually extends CrudRepository<Customer, Long>.
