Update site and community stats

[Ategon]

Requirements

• Is this a feature request? For questions or discussions use https://programming.dev/c/pangora
• Did you check to see if this issue already exists?
• Is this only a feature request? Do not put multiple feature requests in one issue.
• Is this a backend issue? Use the lemmy-ui repo for UI / frontend issues.

Is your proposal related to a problem?

Currently users/month, etc. doesnt take into account actual activity levels very well

Describe the solution you'd like.

This adds comment likes and post likes to the things it pulls from to get the amount of people active

Describe alternatives you've considered.

Tracking everyone who sees a community - would involve much more work than this solution and cant be gotten effectively for instances not using pangora
