fix: set MongoDB max_table_nesting to 0

[karakanb]

Sets max_table_nesting to 0 for MongoDB sources in both the custom query and default collection code paths. Previously this was set to 1, which could result in unwanted nested table expansion.

   Missing assertion for max_table_nesting

   The existing tests don't assert that max_table_nesting is set to 0 on the returned resource. Without this, a future regression (e.g. reverting back to 1) would go undetected.

   Consider adding an assertion in both test_table_instance_is_created and test_table_instance_is_created_with_incremental:

   source = MongoDbSource(table_builder=mongo)
   res = source.dlt_source(uri, table)
   self.assertIsNotNone(res)
   self.assertEqual(res.max_table_nesting, 0)

   **Missing assertion for `max_table_nesting`**
   
   The existing tests don't assert that `max_table_nesting` is set to `0` on the returned resource. Without this, a future regression (e.g. reverting back to `1`) would go undetected.
   
   Consider adding an assertion in both `test_table_instance_is_created` and `test_table_instance_is_created_with_incremental`:
   ```python
   source = MongoDbSource(table_builder=mongo)
   res = source.dlt_source(uri, table)
   self.assertIsNotNone(res)
   self.assertEqual(res.max_table_nesting, 0)
   ```
   
   How can I resolve this? If you propose a fix, please make it concise.
