(synthetics): add Runtime property for syn-python-selenium-1.0 to create synthetics canary

I want to use CDK to create synthetic canary in python and selenium. However, when I try to write some code, i found the there is no matching runtime property.

Not found syn-python-selenium-1.0 from the API docs: - https://docs.aws.amazon.com/cdk/api/latest/python/aws_cdk.aws_synthetics/Runtime.html - https://docs.aws.amazon.com/cdk/api/latest/typescript/api/aws-synthetics/runtime.html#aws_synthetics_Runtime

Is there anyway I can create this type canary by CDK?

Use Case

    const canary = new synthetics.Canary(this, 'MyCanary', {
      schedule: synthetics.Schedule.rate(Duration.minutes(5)),
      test: Test.custom({
        // code: synthetics.Code.fromAsset(path.join(__dirname, 'lambda')),
        code: synthetics.Code.fromInline(
          fs
            .readFileSync(path.join(__dirname, '../../lambda/app.py'))
            .toString()
        ),
        handler: 'index.handler',
      }),
      runtime: synthetics.Runtime.SYNTHETICS_NODEJS_PUPPETEER_3_1,
    });

The synthetics.Runtime.SYNTHETICS_NODEJS_PUPPETEER_3_1 in above code is for NodeJS and Puppeteer

While the workaround works for code that’s fromInline() or fromBucket(), there is currently a requirement for code fromAsset() to have the file structure nodejs/node_modules. The relevant line of code is here and this issue was referenced previously.

It looks like in addition to adding the static method we need to also modify the validateCanaryAsset check to parse between node runtimes and python runtimes. We should be checking that canaries with python runtimes come from within a python folder [source].

Sorry, should have specified the workaround: new Runtime('syn-python-selenium-1.0'). But should keep this open to support this via a static method.
