Drop support for Python 3.10

[drdavella]

Widen the window of support to include 3.11 through 3.14. When we do this we should also update the unit testing matrix in CI/CD.

Also, we can get rid of this warning:

DeprecationWarning: 'importlib.abc.Traversable' is deprecated and slated for removal in Python 3.14

The patch looks like this:
