made changes for M2 mac support

[RobJY]

I've updated package versions in requirements.yml to use conda packages available to M2 macs. Because of an update to flask-sqlalchemy it also required a one-line change to minerva_analysis/server/models/database_model.py. This is explained in the following link:

I tested on my home Ubuntu 22.04 desktop at it seems to run fine.

I found a less invasive change set that doesn't require touching the app code. Rob can you verify whether this works for you too? Here are just the few dependency specs I changed. I also removed the pip section entirely since opencv is available in conda-forge (I got some missing library errors from the pip-installed opencv-python wheel on my mac, anyway, so that wasn't even usable).

- python
- sqlalchemy<2
- opencv=4.5.3

Yes, that works for me on my M2 laptop. You're right, that's better than modifying existing code. Thanks!
