Description of changes:
Hi😀 Thanks for the useful patterns!

This commit forces the Lambda Python runtime to 3.14, but it seems the update was made without verifying that it actually works.

• 795504a

As a result, I get the following error:

╷
│ Error: expected runtime to be one of ["nodejs" "nodejs4.3" "nodejs6.10" "nodejs8.10" "nodejs10.x" "nodejs12.x" "nodejs14.x" "nodejs16.x" "java8" "java8.al2" "java11" "python2.7" "python3.6" "python3.7" "python3.8" "python3.9" "dotnetcore1.0" "dotnetcore2.0" "dotnetcore2.1" "dotnetcore3.1" "dotnet6" "dotnet8" "nodejs4.3-edge" "go1.x" "ruby2.5" "ruby2.7" "provided" "provided.al2" "nodejs18.x" "python3.10" "java17" "ruby3.2" "ruby3.3" "ruby3.4" "python3.11" "nodejs20.x" "provided.al2023" "python3.12" "java21" "python3.13" "nodejs22.x"], got python3.14

So I fixed it.
