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

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