Open Rewrite as a jbang script

As an experiment from asking openrewrite/rewrite#834 I made this little script which is 97% same as the code found in https://github.com/openrewrite/rewrite-maven-plugin.

It lets you run openrewrite on any kind of project.

How to run:

1. Install jbang (https://jbang.dev/download)

2. You can list recipes using:

jbang rewrite@maxandersen/rewrite-jbang discover

1. Try run it with a few recipes:

jbang rewrite@maxandersen/rewrite-jbang --recipes org.openrewrite.java.cleanup.Cleanup,org.openrewrite.java.format.AutoFormat

You can also install the script using: jbang app install https://github.com/maxandersen/rewrite-jbang/blob/master/rewrite.java and just use rewrite directly, i.e.:

rewrite --recipes org.openrewrite.java.cleanup.Cleanup,org.openrewrite.java.format.AutoFormat --dry-run

Limitations:

• does not (yet) offer to refer to dependencies

• totally just slammed together code a slow sunday morning!
