ses_bounce_logging_blog.yml - Unsupported runtime specified for the Lambda Function

[Tim-Brennan]

The Lambda Function Runtime withinn the 'ses_bounce_logging_blog.yml' template is specified as 3.6, this runtime is no longer supported causing the stack creation to fail.
Runtime needs to be increased to 3.9, but I don't know if any python code changes would be required to support this?

I just changed the runtime to 3.8. Not sure what the deprecation schedule is like but it seemed to deploy and work without problem

At the time of writing python 3.7 still has no deprecation date https://github.com/awsdocs/aws-lambda-developer-guide/blob/a83f69b/doc_source/lambda-python.md
