Upgrade to deno 2.x version

[zhorton34]

Deno 2.x Release Candidate has recently been released. We need to update this project to deno version 2.x at some point.

We're a new enough project (less than a week old) so reverse compatibility isn't a huge thing if we want to switch over to use the release candidate before the full release of deno 2.x

Deno 2 has been released and I see you still need help. Let me know what is the plan for the transition to version 2 so I can help you.

I think a good starting point is to check the changes here:
