Unexpected parameter property name in /mapping-rules/marc-authority

Overview:
Steps to Reproduce:

1. Log into some FOLIO environment as User X

2. Fetch the bib-mapping rules by issuing a GET request to mapping-rules/marc-bib

3. Search for occurrences of set_identifier_type_id_by_value

4. Note the parameter "names" that contains a list of names.

5. Fetch the authority mapping rules by issuing a GET request to /mapping-rules/marc-authority

6. Search for occurrences of set_identifier_type_id_by_value

Expected Results:

The parameter should follow the same naming convention, having the name "names"
Actual Results:

The parameter is named "name"
Additional Information:
This makes our data migration scripts crash and is an inconsistency. 

Also, it would be good to add some documentation on Identifier type mapping here:
