chore: revert to prettier-plugin-multiline-arrays@3 for Node.js 20

[GeekyEggo]

prettier-plugin-multiline-arrays@4 introduced an engine dependency of >=22. With Stream Deck plugins running in Node.js, this results in a bad engine warning when installing the package.

Sadly, the alternative is a deprecation warning

run-time-assertions@1.5.2: Use @augment-vir/assert instead

This is, however, better than the bad engine warning.
