Fix contributors missing from filter

[bklaing2]

Purpose

There is a bug when filtering the contributors. non-ORCID identifiers for names were getting picked up when we created the facets, and then filtered out since they were not ORCIDs. This meant that if the top 10 faceted identifiers were mostly or all non-ORCID, then the final result would be a mostly empty or empty array.

closes: datacite/datacite#1891

Approach

Added the following regex filter to the elasticsearch query so that only ORCID iDs are returned in the first place

Reviewer, please remember our guidelines:

• Be humble in the language and feedback you give, ask don't tell.
• Consider using positive language as opposed to neutral when offering feedback. This is to avoid the negative bias that can occur with neutral language appearing negative.
• Offer suggestions on how to improve code e.g. simplification or expanding clarity.
• Ensure you give reasons for the changes you are proposing.
