Publish the Public Layer ARN for aws-lambda-powertools-python-layer-extras in the docs

Is your feature request related to a problem? Please describe
I have followed the alternative solution to publish aws-lambda-powertools-python into my organization's Gov Cloud account suggested in #1166, which works well; however, one of my teams has asked to use the Parser utility and thus requires aws-lambda-powertools-python-layer-extras. I can not find any documented reference to the aws-lambda-powertools-python-layer-extras layer ARN, and the layer ARN is not returned from any CLI calls interacting with with SAR such as:

aws serverlessrepo get-application --application-id arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer-extras

Describe the solution you'd like
Similar to how the public layer ARN is documented as arn:aws:lambda:${AWS::Region}:017000801446:layer:AWSLambdaPowertoolsPython:11, I would like to see a reference for the layer containing the extras so that I am capable of rehosting it within my Gov Cloud account (until such a time as it is hosted publicly within Gov Cloud by the maintainers).

Describe alternatives you've considered
I have considered trying to reference the SAR using SAM/CDK, but to my knowledge the resource arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer-extras is not capable of being referenced from within a Gov Cloud partition.

Additional context
Here is a screenshot of the current state of the documentation without the extras layer ARN for reference:

@ran-isenberg i am sure you can or would like to answer thing one :)

@hilgefjm otherwise you might want to log this issue under the Python project?

[michaelbrewer]

@hilgefjm this is related to Gov Cloud in general #1166

There used be a layer with pydantic.
I dont use it as it's harder to sync the local version of pydantic in the ide and the lambda layer.
I create my own layer.
You can see an example here: https://github.com/ran-isenberg/aws-lambda-handler-cookbook/blob/main/cdk/aws_lambda_handler_cookbook/service_stack/cookbook_construct.py
look at the _build_common_layer function

Thanks for opening your first issue here! We'll come back to you as soon as we can.

Update: @am29d is working on migrating our internal Lambda Layers pipeline to CodePipeline in a Powertools AWS account. Once that's done (~H2), this will reduce our operational overhead and we will consider expanding our public Layers portfolio (ARM, extras).

You can follow progress here: github.com/orgs/awslabs/projects/51/views/11

assigning to @rubenfonseca as we've managed to solve this beautifully for V2

[heitorlessa]

Closing as we're wrap to launch V2.

New Lambda Layer now includes all dependencies, no more need for Extras layer, since we've optimised the size with over 95% reduction
