feat: Allow lambda image builder to use AL2023

[runlevel5]

According to this announcement from AWS, it is now possible to use AL2023 for lambda base image. I think we should remove the warning saying Lambda runner provider only supports Amazon Linux 2.

For time-being, people workaround this limitation by explicitly specify baseDockerImage: 'public.ecr.aws/lambda/provided.al2023'

We are currently using public.ecr.aws/lambda/nodejs as the base image and not provider.al2. We let that image deal with the Lambda interface for us. But it doesn't seem like it would be too difficult to create our own bootstrap file for the provided runtime.

Thanks for the advise. It is indeed quite straightforward to make my own bootstrap file for runtime.

The error message is a bit misleading because public.ecr.aws/lambda/nodejs is not based on public.ecr.aws/lambda/provided.al2

I'll be happy to take a PR for that.

IIRC it's just weird packaging but still AMZL2. You can confirm by checking /etc/os-release.
