When package names match the older-version pattern

[Jack Bates (jablko)]

The current implementation rejects package names that match /^v\d+(\.\d+)?$/. It complains:

Error: Since this type definition includes a header (a comment starting with // Type definitions for), assumed this was a DefinitelyTyped package.
But it is not in a DefinitelyTyped/types/xxx directory: /home/vsts/work/1/s/types/v8

however it clearly is in a "types" directory.

The proposed change would

• continue to allow "types" grandchildren only if they match the older-version pattern
• allow all "types" children, not just those that don't match it
