Make the names of the `{ key label }` types overridable / globally-overridable

[gmiserez]

Currently, the generated resource types are always named TranslatedResourceOf{NameOfOriginalType}.
It should be possible to override the default naming.

services
   .AddRouting()
  .AddGraphQLServer()
  .AddTranslation(c => c
        .AddTranslatableType<HairColor>()
        ...
        .SetNamingConvention("Translated{Name}") // ...or something like that
   )

Additionally it could be interesting to be able to override these names on each field:

    public class Human
    {
        [Translate<MaritalStatus>(resourceKeyPrefix: "MaritalStatus", typeName: "TranslatedMaritalStatus")]
        public MaritalStatus MaritalStatus { get; }
    }
