Describe the bug

When using EnumFeature.WRITE_ENUMS_TO_LOWERCASE, the @JsonProperty values of enum fields are ignored.

Version Information

2.18.1

Reproduction

class ObjectMapperTest {

  public enum Sauce {
    @JsonProperty("Ketchup")
    KETCHUP,
  }

  ObjectMapper objectMapper = new ObjectMapper()
      .configure(EnumFeature.WRITE_ENUMS_TO_LOWERCASE, true);

  @Test
  void shouldUseJsonProperty() throws JsonProcessingException {
    assertEquals("\"Ketchup\"", objectMapper.writeValueAsString(Sauce.KETCHUP));
  }
}

Results in:

org.opentest4j.AssertionFailedError:
