docs(contributing): update .luarc.json docs for gitignored setup

The .luarc.json is now gitignored (not committed), so update the
contributing guide to reflect that developers must copy the example
config locally instead of editing a committed file.

Also document that SMODS scanning .json mod directories produces a
harmless log error, and add the Balatro globals (localize,
get_blind_amount, get_compressed, save_run, compress_and_save) that
were recently removed from inline diagnostic suppressions.
