Be able to use `count_query` on `ext.sqlmodels.paginate` and `ext.sqlalchemy.paginate`

[moumoutte]

Do not use the boolmethod of count_query as it's not evaluating to a boolean here and instead detect if it's None or not. Also add the count_query as a valid parameter of fastapi_pagination.ext.sqlmodel.paginate

If I understand properly your comment, you ask me if I could add the count_query param to the ext.sqlalchemy.paginate function ?

I think this param is already present here : https://github.com/uriyyo/fastapi-pagination/blob/main/fastapi_pagination/ext/sqlalchemy.py#L241 and here https://github.com/uriyyo/fastapi-pagination/blob/main/fastapi_pagination/ext/sqlalchemy.py#L226

Only the function marked as deprecated has no count_query param.

I guess this is a good thing to not maintain a feature on deprecated function. But if you really want to it , I could provide it. Let me know !

@moumoutte My bad, I forgot that it already has count_query param 😅
