stylua 2.2.0

Looks like an issue in our upstream full-moon parser. The support for p is present, but is only enabled for Lua52 mode and not for LuaJIT: https://github.com/Kampfkarren/full-moon/blob/47d4bf94104c0de70e26075e0f2c991b97af64ef/full-moon/src/tokenizer/lexer.rs#L1103

If you're installing stylua from cargo, make sure to include the features flag. If you enable both lua52 and luajit it might be a good enough workaround for you
