Docs: Parameter Store aliases documentation incorrect

[speshak]

What were you searching in the docs?

I wanted to look up the layer ARN using a Terraform data resource. When following the example in the documentation I was getting parameter not found errors. I found that when SSM parameter store aliases were introduced in 3.4.0, the release notes state that the python version in the SSM path should include the .:

<python_version> with your desired Python version (e.g., "python3.8", "python3.9", etc.).

The current documentation about using the SSM parameters states

{python_version} is the Python version without the period (.), e.g., python313 for Python 3.13

Is this related to an existing documentation section?

https://docs.powertools.aws.dev/lambda/python/latest/#aws-ssm-parameter-store

How can we improve?

I believe the documentation should be updated to reflect that the parameter name includes the period in the python version. When I switched my TF code to include it, the parameter was found as expected.

Got a suggestion in mind?

I believe the documentation should be updated to reflect that the parameter name includes the period in the python version.

Acknowledgment

• I understand the final update might be different from my proposed suggestion, or refused.

Hey @speshak! Thanks for opening this issue to improve our documentation. You're right, we need to update our documentation to reflect the correct parameter name and avoid customers wasting time with incorrect information.

Would you like to send a pull request to update this? I'd really appreciate your contribution here.
