refactor: using latest install and font patch method

This updates the existing PR to:
1) install on `ucore` (not `ucore-minimal`)
2) install latest release (in case we get one)
3) use font patching from 45 drives to fix missing fonts

This approach is what I've been testing for months and was suggested to
me by @bketelsen based on his Homer image:
