Docs: HomePage - Fix syntax errors in SAR CDK example

[michaelbrewer]

Expected Behaviour

Code examples should have valid python syntax, line highlights should be correct and Powertools version should be current.

Current Behaviour

When copying the code example for SAR - CDK you will get the following error:

Code snippet

from aws_cdk import core, aws_sam as sam, aws_lambda

POWERTOOLS_BASE_NAME = 'AWSLambdaPowertools'
# Find latest from github.com/awslabs/aws-lambda-powertools-python/releases
POWERTOOLS_VER = '1.23.0'
POWERTOOLS_ARN = 'arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer'

class SampleApp(core.Construct):

    def __init__(self, scope: core.Construct, id_: str) -> None:
        super().__init__(scope, id_)

        # Launches SAR App as CloudFormation nested stack and return Lambda Layer
        powertools_app = sam.CfnApplication(self,
            f'{POWERTOOLS_BASE_NAME}Application',
            location={
                'applicationId': POWERTOOLS_ARN,
                'semanticVersion': POWERTOOLS_VER
            },
        )

        powertools_layer_arn = powertools_app.get_att("Outputs.LayerVersionArn").to_string()
        powertools_layer_version = aws_lambda.LayerVersion.from_layer_version_arn(self, f'{POWERTOOLS_BASE_NAME}', powertools_layer_arn)

        aws_lambda.Function(self,
            'sample-app-lambda',
            runtime=aws_lambda.Runtime.PYTHON_3_8,
            function_name='sample-lambda',
            code=aws_lambda.Code.asset('./src'),
            handler='app.handler',
            layers: [powertools_layer_version]
        )

Possible Solution

Solution for this in included in PR #1113 this also fixes the line highlights and includes the latest version of powertools

from aws_cdk import aws_lambda
from aws_cdk import aws_sam as sam
from aws_cdk import core

POWERTOOLS_BASE_NAME = "AWSLambdaPowertools"
# Find latest from github.com/awslabs/aws-lambda-powertools-python/releases
POWERTOOLS_VER = "1.25.10"
POWERTOOLS_ARN = "arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer"


class SampleApp(core.Construct):
    def __init__(self, scope: core.Construct, id_: str) -> None:
        super().__init__(scope, id_)

        # Launches SAR App as CloudFormation nested stack and return Lambda Layer
        powertools_app = sam.CfnApplication(
            self,
            f"{POWERTOOLS_BASE_NAME}Application",
            location={"applicationId": POWERTOOLS_ARN, "semanticVersion": POWERTOOLS_VER},
        )

        powertools_layer_arn = powertools_app.get_att("Outputs.LayerVersionArn").to_string()
        powertools_layer_version = aws_lambda.LayerVersion.from_layer_version_arn(
            self, f"{POWERTOOLS_BASE_NAME}", powertools_layer_arn
        )

        aws_lambda.Function(
            self,
            "sample-app-lambda",
            runtime=aws_lambda.Runtime.PYTHON_3_8,
            function_name="sample-lambda",
            code=aws_lambda.Code.asset("./src"),
            handler="app.handler",
            layers=[powertools_layer_version],
        )

Steps to Reproduce

1. Copy code for the CDK example in https://awslabs.github.io/aws-lambda-powertools-python/latest/#sar
2. Try to compile python code.
