[Catalog, Documentation]: Improvements to Catalog of games docs page

[edwardchalstrey1]

Requested documentation improvement

• Pre-requisites: Rename Game.comment to Game.description #755 Add initial version of games catalog #753
• If a lot of games in the catalog have long descriptions as well as titles, we should display this information in documentation
• Add an extra field to the pandas df from games() and the table in the docs that includes the Game.description field - this may need to be hidden by default
• Remove the old samples page completely
• Add ability to download game files from catalog game docs: Update the Catalog game page to include download links for game files
