chore(several samples) Updating all instances of Pytest up to version 9.0.3 Part III (#14233)

* chore(,ultiple samples): update pytest and standardize python test matrix for a-m samples

 - Bump pytest to 9.0.3 (pinned to Python >= 3.10)
 - Update noxfile configs to only test against Python 3.10 and 3.14
 - Upgrade Dockerfile base images and Beam SDKs to Python 3.14

* Added missing directory e changes.

* Ammend docker files to use python 3.14 properly, ignored versions to
work only on python 3.14, and removed outdated comments.

* rolled back endpoints/getting-started/ since the docker file pulls a python 2.7
runtime. Will be left to be investigated at a later date.
