Description
When applied to an enum property, Jackson's @JsonValue automatically provides a two-way translation that is likely to be more efficient than the generated fromValue. The @JsonCreator annotation is unnecessary and should be retired.
Applies to 3.3.4 and 4.0.0-beta3.

Research direction
Start by tracing the Java enum generation path and locating where @JsonCreator and fromValue are emitted; the issue names no files or tests. Verify how @JsonValue handles enum deserialization, then confirm that generated Java enums omit the unnecessary annotation while retaining the requested two-way translation.
