ci: remove testing python 3.7 and 3.8, add testing python 3.12 (#498)

* ci: remove testing python 3.7 and 3.8, add testing python 3.12 and 3.13

* remove 3.13 for now

* test examples against 3.12 too

* try examples with 3.12 allowed

* revise python version in examples again to allow 3.12

* chore: use newer grpcio for python 3.13

Because grpcio 1.66.2 is the minimum version that supports python
3.13, we add a conditional dependency on that version.

* ci: run ci for python v3.13

* revert: momento-wire-types shouldn't be in test deps

Previously I mistakenly cut and paste this to the test deps section.

* chore: add note about minimum grpcio version
