Allow recipe parameters to be specified from the command line

[blipper]

What problem are you trying to solve?

Reduce friction to using OpenRewrite

Describe the solution you'd like

https://docs.openrewrite.org/running-recipes/running-rewrite-on-a-gradle-project-without-modifying-the-build#step-3-optional-create-a-custom-declarative-recipe

Right now the only way to pass parameters to recipes is creating a custom recipe. It would be great to have a command line mechanism similar to

bb rewriteRun  -Drewrite.activeRecipe=foo.Bar -Drewrite.params.foo.Bar.myParam1=paramValue

Have you considered any alternatives or workarounds?

Additional context

Are you interested in contributing this feature to OpenRewrite?

Yes.

Thanks for the offer to help @blipper ! For context: we added similar support for the Maven plugin in openrewrite/rewrite-maven-plugin#816, as documented. Ideally these implementations look alike as much as possible.
