Prettier 3.x Plugin Loading New Behavior #1798

Hello, Prettier v3.x changed the way it load plugins. Now plugins are not loaded by default anymore, instead users have to manually pass a --plugin=prettier-plugin-name, or configure it in a configuration file via plugins: ['prettier-plugin-name'].

I tried something like this to see if it would work:

spotless {
    // ...
    java {
        // ...
        prettier(['prettier': '3.0.2', 'prettier-plugin-java': '2.3.0'])
                .config(['plugins': ['prettier-plugin-java'], 'parser': 'java', 'tabWidth': 4, 'printWidth': 120, 'useTabs': false])
        // ...
    }
}

But gave me the error:

Only values of type 'String', 'JsonRawValue', 'Number' and 'Boolean' are supported. You provided: [java, [prettier-plugin-java], 120, 4, false]

Am I missing something? I saw prettier v3 support was added in #1760, but I didn't see any noticeable docs updates about the plugin loading changes.

Note, just by doing

prettier(['prettier': '3.0.2', 'prettier-plugin-java': '2.3.0'])
  .config(['parser': 'java', 'tabWidth': 4, 'printWidth': 120, 'useTabs': false])

The following error happens:

Unexpected response status code at /prettier/format [HTTP 500] -- (Error while formatting: ConfigError: Couldn't resolve parser "java".)

Which is why I tried to go the manual plugin loading route.
