Remove redundant Jackson 3 feature flag configurations

Recipe IDorg.openrewrite.java.jackson.RemoveRedundantFeatureFlags
Artifactorg.openrewrite.recipe:rewrite-jackson

Remove ObjectMapper feature flag configurations that set values to their new Jackson 3 defaults. For example, disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES) and configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false) are redundant since this is now disabled by default in Jackson 3.
