Lambda Layers With Containers

[metaskills]

Learning from customink/crypteia#17 and having a need to use Ruby Libvips with a few projects that need to move to Containers AND not be slowed down by building their own Libvips each time. Example:

FROM ghcr.io/customink/ruby-vips-lambda-layer:8.12.2.1 AS ruby-vips-lambda
FROM public.ecr.aws/lambda/ruby:2.7
COPY --from=ruby-vips-lambda /opt /opt

This pull request also introduces a development container. I was able to use an 8 CPU one during this work to keep the builds fast. NOTE: After I merge this work in I will ensure the release task runs and we get those containers published so the docs actually work.
