ORCID ID ending in "X" is rejected by GitLab profile validation

This bug happens on GitLab.com

Summary

GitLab rejects valid ORCID identifiers ending with an X, such as 0000-0002-2189-706X, which is a valid checksum.

Steps to reproduce

1. Go to https://gitlab.com/-/profile
2. Enter 0000-0000-0000-000X into the ORCID field
3. Update profile settings

What is the current bug behavior?

An error message is displayed:

User detail orcid must contain only a orcid ID.

What is the expected correct behavior?

If instead of 0000-0000-0000-000X you use 0000-0000-0000-0000, you will get the proper behavior, with the message
