Fix Lambda python version for previous versions of ParallelCluster.
Browse files Browse the repository at this point in the history 
PC 3.11.1 updated the Lambda layer to use Python 3.12.
Previous version required Python 3.9.

Set the Lambda Python runtime based on the ParallelCluster version so that
the application continues to work on older versions of PC.

This bug was introduced in #270.
