[docs] Update deps (#2332)

## Summary

I wanted to update dependencies to see if we can get rid of some
Dependabot warnings. Also wanted to modernize our devbox.json a bit to
make the onboarding process easier. Not totally working though.

## How was it tested?

I'm able to do `devbox run serve` but I only get 404s.

If I do build/start I get:

`Error: Cannot mix different versions of joi schemas` 

Not sure if I introduced this issue.
