[Feature Request] Add ./gradlew :plugins:xyz:run

[dblock]

Is your feature request related to a problem? Please describe

Developers want an easy way to run a plugin during development.

Describe the solution you'd like

In #11844 we've added the ability to do ./gradlew run -PinstalledPlugins="['plugin1', 'plugin2']". For one plugin this is a bit of a convoluted syntax (the name can't be plugins), so I'd like to be able to do ./gradlew :plugins:xyz:run when developing an xyz plugin in the plugins folder which should end up doing what ./gradlew run -PinstalledPlugins="['xyz']" does.

Describe alternatives you've considered

Currently you can modify gradle/run.gradle as follows.

testClusters {
  runTask {
    testDistribution = 'archive'
    if (numZones > 1) numberOfZones = numZones
    if (numNodes > 1) numberOfNodes = numNodes
    // add plugin(s) to load in ./gradlew run
    plugin(':plugins:xyz') // <-------- add this to load xyz plugin
  }
}

Additional context

Some people might want to load more than one plugin via command line.

It's the same intent but a different syntax.
