types defined in subpackages are treated as valid types

[matt2e]

Steps:

• Make a module called parent
• Make a subpackage within the module called child

package child

type ChildStruct struct {
  Name string
}

• In parent, use this type

//ftl:data
type ParentResponse struct {
  Message string            `json:"message"`
  Data    child.ChildStruct `json:"data"`
}

Expected:

An error saying you can't use types from subpackages

Actual result:

schema:

data ParentResponse {
  message String +alias json "message"
  data parent.ChildStruct +alias json "data"
}

Not only is it not making an error when extracting the schema, the type parent.ChildStruct doesn't exist.
