Find text-direction changes

Recipe IDorg.openrewrite.java.security.FindTextDirectionChanges
Artifactorg.openrewrite.recipe:rewrite-java-security

Finds unicode control characters which can change the direction text is displayed in. These control characters can alter how source code is presented to a human reader without affecting its interpretation by tools like compilers. So a malicious patch could pass code review while introducing vulnerabilities. Note that text direction-changing unicode control characters aren't inherently malicious. These characters can appear for legitimate reasons in code written in or dealing with right-to-left languages. See: https://trojansource.codes/ for more information.
