liblua5.4 missing from 'Focal' suite of Ubuntu packages

[Trogluddite]

Running a docker build for the Ubuntu image currently fails:

I attempted to downgrade the liblua version by setting ARG lua_version=5.3 (the latest version present in the Focal suite), but the build fails later, on Cabal dependencies that expect version 5.4.

I think the fix here is to update the Ubuntu base image to Jammy, which does include liblua @ 5.4.
