Describe the bug

Apprunner supports two Python Runtimes: 3 and 311 as documented here: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-apprunner-service-codeconfigurationvalues.html

PYTHON_311 is missing from https://github.com/aws/aws-cdk/blob/main/packages/%40aws-cdk/aws-apprunner-alpha/lib/service.ts#L210

Expected Behavior

It is expected that the CDK should make all supported runtimes available.

Current Behavior

It only supports Python_3 (this translates to the extremely old Python 3.8)

Reproduction Steps

apprunner_alpha.Service(
self,
"My Web Site",
instance_role=web_instance_role,
source=apprunner_alpha.Source.from_git_hub(
repository_url="",
branch="main",
configuration_source=apprunner_alpha.ConfigurationSourceType.API,
code_configuration_values=apprunner_alpha.CodeConfigurationValues(
runtime=apprunner_alpha.Runtime.PYTHON_3,
port="5000",
start_command="",
build_command="",
environment_variables={},
),
connection=apprunner_alpha.GitHubConnection.from_connection_arn(
web_github_arn
),
),
)

Possible Solution

/**

• Python 3.11
  */
  public static readonly PYTHON_311 = Runtime.of('PYTHON_311')
