feat: add Dockerfile (#8315)

This PR adds an official Dockerfile for Puppeteer. The content of the Dockerfile is practically the same as documented in troubleshooting.md:

1) It installs chrome-stable and dependencies via apt-get.
2) it installs a local Puppeteer build into the docker user's home folder.
3) configures required permissions for the user.
4) outputs licenses into the THIRD_PARTY_NOTICES file.

The local Puppeteer build is created by `docker/pack.sh` which is meant to be used in CI. This PR also includes a GitHub action that would build a docker image and run a smote test inside of it.

The next step would be actually publishing the docker image from GitHub Actions to GitHub Registry.
