Migrate mapper setter calls to builder pattern

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

In Jackson 3, JsonMapper and other format-aligned mappers are immutable. Configuration methods like setFilterProvider, addMixIn, disable, enable, etc. must be called on the builder instead. This recipe migrates setter calls to the builder pattern when safe, or adds TODO comments when automatic migration is not possible.
