Cannot convert between types that have an implicit cast in Indexer Properties

Json serializers will often convert the numbers in a dictionary to the smallest type, "90" will be converted to byte. When this dictionary has indexerProperty, the conversion will fail if the deserialized value has not exactly the same type as the indexerProperty type ( even if there is an implicit conversion like int=>long ).

### Code
```C#
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;

public class User
{
public int Id { get; set; }
public Dictionary Data { get; set; }
public long Number { get; set; }
}

public class SqlServerDbContext : DbContext
{
public SqlServerDbContext(DbContextOptions options) : base(options)
{ }

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
var etb = modelBuilder.Entity();
etb.HasKey(x => x.Id);
etb.Property(x => x.Number);
etb.OwnsOne(x => x.Data, x =>
{
x.IndexerProperty(typeof(long), "Number");
});
}
}

class Program
{
static void Main(string[] args)
{
var sc = new ServiceCollection();
var guid = Guid.NewGuid();
sc.AddDbContext(op => op.UseSqlServer(@"Server=(localdb)\MSSQLLocalDB;Integrated Security=true;DataBase=" + guid));
using (var provider = sc.BuildServiceProvider())
{
using (var scope = provider.CreateScope())
using (var dbcontext = scope.ServiceProvider.GetService())
{
dbcontext.Database.EnsureCreated();
}
var user = new User()
{
Number = 5
};
using (var scope = provider.CreateScope())
using (var dbcontext = scope.ServiceProvider.GetService())
{
dbcontext.Set().Add(user);
dbcontext.SaveChanges();
}
var user2 = new User()
{
Data = new Dictionary() { { "Number", 5 } }
};
using (var scope = provider.CreateScope())
using (var dbcontext = scope.ServiceProvider.GetService())
{
dbcontext.Set().Add(user2);
dbcontext.SaveChanges();
}
}
}
}
```
