🔧 Hide the "buy tickets" links since tickets are no longer on sale

[drewbrew]

Pages affected:

• Home page
• Top nav
• Schedule page
• Ticket page
• Tutorials schedule page

Switches the HTML comments to template contents so the links aren't visible in the HTML.

I couldn't run this locally (different machine that's not setup), but I did a code search and found a few more we should comment out.
