Update preferred_python3 to 3.10. Python 3.7 is no longer supported.

If memory serves, this is also the Python version in the latest Docker image of alpine-compass-python-perl-node. We could also use a later version; I was just being conservative.

I believe the plan is actually to move to 3.11. See #672. @hyanwong may be in the process of making this change?

Personally, I've been on 3.10, which is what comes with Ubuntu 22.04.

[hyanwong]

It seems like the new OneZoom server will be running 3.10 in a few days, so I think that should be our target.

Ok, I applied the change both here and to the Dev Container pull request. Note that this new version of Python also requires a more recent version of web2py in order to use the web2py.py server script (or else you get an error from a deprecated threading library call), so I also updated that in my Dev Container, which means it no longer aligns with the version configured in the main Dockerfile. Should we update that too?

[hyanwong]

Yes, I think we should update the Dockerfile to match. It's good to keep this stuff reasonably up-to-date anyway.

Sent a pull request to update the Dockerfile to align: OneZoom/OZtree-docker#3

[lentinj]

I'll be merging #711 soon, which does this along with a bunch of other stuff, so will close this and merge that if that's okay.

@hyanwong I'd merge OneZoom/OZtree-docker#3 but I'm not allowed to.
