Replace javax.security.auth.Policy with java.security.Policy

[BhavanaPidapa]

What's changed?

What's your motivation?

I used org.openrewrite.java.ChangeType for the recipe RemovedPolicy

Anyone you would like to review specifically?

@cjobinabo @timtebeek

Have you considered any alternatives or workarounds?

Since it was not possible to test the recipe. I created sample files, created a local plugin using
./gradlew publishToMavenLocal then ran it in the Java8 Sample App using mvn rewrite:dryRun

Attaching the rewrite.patch file
rewrite.patch

Checklist

• I've added unit tests to cover both positive and negative cases
• I've read and applied the recipe conventions and best practices
• I've used the IntelliJ IDEA auto-formatter on affected files

For any future PR: no need to update these copyright headers; we typically keep the year on when they were first introduced.

Neat addition @BhavanaPidapa, thanks for adding the recipe and verifying it locally. Indeed it can be difficult to unit test classes removed in newer Java versions, but this should be ok.

One small suggestion to update the phrasing of the displayed name and description, but otherwise good to merge from my end. I'll leave it up to @cjobinabo to do a final check and merge.

I've gone ahead and commited the suggestion. Thanks for looking at this @timtebeek

Great! Then feel free to merge whenever suits you best. :)
