Add feature and description overview list
Antora has a lot of features. We need to create a curated list of these capabilities/features with short descriptions so that people can get an overview of what the pipeline provides. This list may or may not be grouped into categories.
Done Criteria:
- List of Antora's capabilities/features
- Short descriptions for each
- High level categorization if it seems appropriate
- Notes regarding any terminology that isn't satisfactory yet
- Notes regarding features or descriptions that may not resonate with users
- Notes may spawn additional issues
- Resulting file added to ROOT module
