Looks like there's a conflict between Python 3.14 and assertion rewriting in pytest 6.2.4. I'll track down a suitable minimum pytest version and update accordingly. |

I had to set the minimum pytest version for Python 3.14 to pytest 7.3.2, because older versions of pytest use ast.Str, which was removed in 3.14.

The main purpose of this commit is to enable testing on Python 3.14 in CI. But Python 3.14 requires a different minimum version of pytest from any earlier version, meaning that we now have three different minimum pytest versions that need to be tested depending on the Python version, and that's very complicated to express by including and excluding specific configurations as we were doing before. So I refactored the matrix of versions to take advantage of the ability to have objects as matrix values, meaning that each Python version can be accompanied by the specific minimum pytest version it requires in the matrix. This is much easier to understand and maintain, and it should also have us running fewer CI jobs overall (since we're no longer going to run combinations like pytest 6.2.4 on Python 3.7-3.9, which served no purpose).
