Migrate Log4j 2.x Appender to logback-classic equivalents

** org.openrewrite.java.logging.logback.Log4jAppenderToLogback** Migrates custom Log4j 2.x Appender components to logback-classic. This recipe operates on the following assumptions: 1.) The contents of the append() method remains unchanged. 2.) The requiresLayout() method is not used in logback and can be removed. 3.) In logback, the stop() method is the equivalent of log4j's close() method. For more details, see this page from logback: Migration from log4j.
