Mapping `init` or `required` properties does not use `PropertyNameMappingStrategy`

Describe the bug Mapping to required or init properties doesn’t use the PropertyNameMappingStrategy.

Expected behavior Mapping should use PropertyNameMappingStrategy

Code snippets

[Mapper(PropertyNameMappingStrategy = PropertyNameMappingStrategy.CaseInsensitive)]
public static partial class Mapper
{
    public static partial B Map(A src);
}
public class A
{
    public int Value { get; set; }
}
public class B
{
    // can also be required
    public int value { get; init; }
}

Generated code

public static partial global::Riok.Mapperly.Sample.B Map(global::Riok.Mapperly.Sample.A src)
{
    var target = new global::Riok.Mapperly.Sample.B();
    return target;
}

@cristianUrbina FYI here is a guide on how to request a review: https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/requesting-a-pull-request-review. However, I just noted this may only be possible for accounts having write access to the repository…
