.dockerignore: Use an allowlist approach for selective builds #12827
Description
For very selective builds, a robust strategy is to ignore everything by default (*) and then use the negation pattern (!) to explicitly include only the necessary files or directories.
Example:
# Ignore everything
*
# Include only what's needed
!src/
!package.json
!package-lock.json

This is an issue. We should fix this but IMO, it is low priority. Since this image is a simulator docker image and I am not sure about it's usage currently other than some CI jobs.
