Update Request (Plugin/Nixpkgs)

Feature description

Prettier supports formatting json files and with projects that use prettier sometimes the json format (from jsonfmt) can look very different to what prettier returns/formats and it can be confusing/annoying to deal with
Id love to have support for setting prettier as the formatter for json

Currently there's no good framework to enable an existing formatter for alternative languages, however, you can either configure Conform manually via the setupOpts.formatters option or submit a PR to add prettier as an available formatter for the JSON module. It's quite trivial to do.
