For synonyms show original term

Problem/Motivation

Thanks to everyone who helped adding synonyms support. This is working great and much better than my implementation in ✨ Glossary term synonyms/aliases Fixed . I could also easily switch to this, by selecting the field containing synonyms in the taxonomy as synonym provider in the the synonyms configuration.

The only that's missing compared to my patch is the ability to display the original glossary term when a synonym is highlighted. In my patch it would show the original term followed in brackets by the synonym that is being highlighted.

Steps to reproduce

Follow steps to add synonym support though a field. Add a synonym. In the popup only the synonym is shown, but not the original term

Proposed resolution

Add setting to show original term when a synonym is found, e.g.

TERM (SYNONYM)
