Add a squash version of alpine-chrome:latest

[jlandure]

Context

💡 This is only an idea.
To get a smaller image, we could use the experimental features docker image build --squash.
But it's not working on the Docker Hub. See docker/hub-feedback#955

Alternatives

I can do it on my laptop and upload it.
Here is the difference: only ~5MB

docker image inspect zenika/alpine-chrome --format='{{.Size}}'
393543827
docker image inspect zenika/alpine-chrome:latest-squash --format='{{.Size}}'
388574396

Conclusion

Not very useful at the moment. 😅
