Description

cloud_scheduler/snippets/app.yaml still uses runtime: python37. That runtime is deprecated on App Engine, and it can't install the sample's requirements: Flask 3.1.3 needs Python 3.9 or newer, and Werkzeug 3.1.9 needs 3.10 or newer. This changes it to python313, the runtime most appengine/standard_python3 samples use.

This is a one-line config change. I did not deploy it.

Code Review

This pull request updates the App Engine runtime in app.yaml from python37 to python313. The review feedback correctly points out that python313 is not yet supported by the Google App Engine standard environment and recommends using python312 instead to avoid deployment failures.

Thanks for sharing this update; these samples have been refactored and this no longer applies.
