mapster tool generates non-public interface method/property implementation

[zaigr]

When generating mapper from interface containing mapping method/property with internal classes mapster tool generates internal implementation of this method/property

• Mapster.Core v1.2.0
• mapster.tool v8.2.1
• executed on net5

[Mapper(IsInternal = true)]
internal interface IMyMappers
{
    PocoDto Map(Poco source);

    Expression<Func<Poco, PocoDto>> ProjectToDto { get; }
}

public record Poco(string Name, string Description);

internal record PocoDto(string Name, string Description);

Generated mapper class is:

internal partial class MyMappers : IMyMappers
{
    internal Expression<Func<Poco, PocoDto>> ProjectToDto => p1 => new PocoDto(p1.Name, p1.Description);
    internal PocoDto Map(Poco p2)
    {
        return p2 == null ? null : new PocoDto(p2.Name, p2.Description);
    }
}

CS0737: 'MyMappers.Map(Poco)' cannot implement an interface member because it is not public. CS0737: 'MyMappers.ProjectToDto' cannot implement an interface member because it is not public.

Maybe internal class with proper implementations should be generated even in case MapperAttribute.IsInternal hasn't been specified

@zaigr After looking at the code I suspect that this is a shortcoming in the ExpressionTranslator library. It seems like it would be an easy fix though (take a look at line 1179-1181 and 1210-1212).
