BewitRegistrationBuilder.GetRepository should be of Type Func<IServiceProvider, INonceRepository> to facilitate the use of registered services

Is your feature request related to a problem? Please describe.
Currently, the property BewitRegistrationBuilder.GetRepository is of type Func<INonceRepository>. This comes with certain limitations, as it is therefore not easily possible to consume services from the serviceProvider during the initialization of the NonceRepository.

Example from the MongoDB persistence package:

        public static BewitRegistrationBuilder UseMongoPersistance(
            this BewitRegistrationBuilder builder,
            BewitMongoOptions options)
        {
            ...
            var client =
                new MongoClient(options.ConnectionString);
            IMongoDatabase db =
                client.GetDatabase(options.DatabaseName);

            builder.GetRepository = () => new NonceRepository(
                db, options.CollectionName ?? nameof(Token));

            return builder;
        }

Describe the solution you'd like
BewitRegistrationBuilder.GetRepository should be of type Func<IServiceProvider, INonceRepository>. That way we could use registered services to initialize the NonceRepository:

builder.GetRepository = (ctx) => new NonceRepository(
                ctx.GetRequiredService<IMongoDatabase>(), options.CollectionName ?? nameof(Token));

We can keep the old implementation and add an overload to don't introduce a braking change
