ORCID field validator doesn't permit the inclusion of "sandbox" in the ID string

Context : OJS 3.3.0-13 ; ORCID plugin v.

Testing with ORCID Sandbox (Member)

The “(sandbox.)?” part for the regex in this fix (Orcid Regex for sandbox · pkp/pkp-lib@9d0abf7 · GitHub) didn’t seem to be included in my 3.3.0-13 instance (pkp-lib/ValidatorFactory.inc.php at 3_3_0-13 · pkp/pkp-lib · GitHub). Had to add it manually. Did I miss something here?
