Micronaut 4 regression: @EachProperty with enum-type @Parameter does not work

[eager-signal]

Expected Behavior

In Micronaut 3, the following works:

// Configuration.java
@EachProperty("config")
public record Configuration(@Parameter MyEnum myEnum,
                            @NotEmpty List<@NotBlank String> cities) {

    public enum MyEnum {
        SUMMER,
        WINTER
    }
}

// ConfigurationTest.java
@MicronautTest
@Property(name ="config.summer.cities", value = "barcelona,atlanta,sydney")
@Property(name = "config.winter.cities", value = "albertville,lillehammer,nagano")
public class ConfigurationTest {

    @Inject
    private List<Configuration> configs;

    @Test
    void testEnumParameter() {
        assertEquals(2, configs.size());
        assertTrue(configs.contains(new Configuration(Configuration.MyEnum.SUMMER, List.of("barcelona", "atlanta", "sydney"))));
        assertTrue(configs.contains(new Configuration(Configuration.MyEnum.WINTER, List.of("albertville", "lillehammer", "nagano"))));
    }
}

Actual Behaviour

After upgrading to Micronaut 4, the test fails with:

io.micronaut.context.exceptions.BeanInstantiationException: Error instantiating bean of type  [com.example.Configuration]

Message: Missing bean argument value: myEnum
Path Taken: ConfigurationTest.configs --> new Configuration([MyEnum myEnum],List cities)

Steps To Reproduce

Run the above tests. The example project has a working main branch (Micronaut 3). The micronaut-4 branch illustrates the same code failing after the upgrade.
