Subject: [PATCH] Add XML documentation for GetReferenceTypes method

This commit introduces XML documentation comments to the
GetReferenceTypes method in the HistoryController class.
The comments clarify the method's purpose, indicating that
it retrieves available reference types and returns them
as key-value pairs, along with a summary and return type
information.
