Consider using Intersphinx to grab remote Glossary terms

If you don't want to copy-paste Glossary terms from `6.docs.plone.org`, you can use a nifty trick with Intersphinx to define them in the external documentation at `6.docs.plone.org`. The downside is that the user would be taken to an external site, but there is an external link indicator on that link. This configuration already exists.

You would also need to remove the file `glossary.md`, unless you want to define terms that are unique to this project.

See https://github.com/plone/volto/pull/3779#issuecomment-1281684119.

Locate the existing Intersphinx configuration and inspect glossary.md, using the linked discussion for context. The work is complete when glossary terms resolve from 6.docs.plone.org, external-link behavior remains acceptable, and project-specific terms are retained if needed.
