frontend/ui: missing element to display knowledge links

[aviv-julienjehannet]

Describe the bug
The business glossary format allows knowledge links. They are correctly stored in the backend but nothing is displayed in the default Term Group page.

To Reproduce
Steps to reproduce the behavior:

1. Ingest https://github.com/datahub-project/datahub/blob/master/metadata-ingestion/examples/bootstrap_data/business_glossary.yml
2. Go to one Term Group having some links: as "Wiki link for classification" in Classification node
3. No way to see or edit the ingested links

Expected behavior
We should have the same interface than a Glossary Term

Desktop (please complete the following information):

• OS: Windows
• Browser: Firefox
• Version 132

Additional context
Using datahub CLI, we can retrieve the ingested links.
