SharedTypeEntity don't work with bulk operations

Lines 154 to 164 in 580e0c3

	var entityType = type is null ? null : context.Model.FindEntityType(type);
	if (entityType == null)
	{
	type = entities.FirstOrDefault()?.GetType() ?? throw new ArgumentNullException(nameof(type));
	entityType = context.Model.FindEntityType(type);
	HasAbstractList = true;
	}
	if (entityType == null)
	{
	throw new InvalidOperationException($"DbContext does not contain EntitySet for Type: {type?.Name}");
	}

The usage of FindEntityType breaks bulk operations on SharedTypeEntity.

Possible solutions:

1. Allow passing a specific IEntityType via parameters or bulkconfig
2. Allow running bulk methods on a specific DB Set instead of just the context; this aligns with official EF core behavior: https://learn.microsoft.com/en-us/ef/core/change-tracking/miscellaneous#dbcontext-versus-dbset-methods

Bulk methods has parameter Type as last argument of function.
BulkInsert<T>(this DbContext context, IEnumerable<T> entities, BulkConfig? bulkConfig = null, Action<decimal>? progress = null, Type? type = null)
