M2M lookups are adding up to the query count, we need to adjust tests to that.

@model-bakers/core would love to get your opinion here. I solved the original issue, but it adds extra queries to resolve M2M relations (which I expected). However, due to QuerySet.bulk_create not returning pks in old SQLite versions (and Django < 4.0), there is an extra step that adds even more queries (however, I limited it to not affect Django 4.0+ users). The other option would be to explicitly say that we are not supporting M2M properly in QuerySet.bulk_create, which is also not desirable... |

Describe the change
Extending logic of
_save_related_objsthat was added in #206.This is optimized because of
bulk_createuse on through model, but it is still quite heavy on queries.I had to switch to Ubuntu 22 in CI to upgrade default SQLite version which supports returning pks in bulk create operations.
