Feature request: `publish local --m2`

[kubukoz]

Is your feature request related to a problem? Please describe.

Sometimes you just want to publish to ~/.m2. Most JVM build tools provide this, sbt/mill included.

Describe the solution you'd like

Some configuration or flag to make publish local go to m2Local.

Describe alternatives you've considered

Manually copying the files or using a ~~different~~ build tool.

Additional context

Smithy CLI doesn't like ivy2Local 😅
