Subject: [PATCH] Backport: fix varargs (i.e. <n+:n>) signature validation

Using <n+:n> signature, validate will return the first arg n times.
As we're based on this impl the fix should be backported

Original fix here:
https://github.com/dashjoin/jsonata-java/commit/3849b71066908de22e70fa076ff21e19ee5a11d6

Test case:
