Installed latest docker-desktop as well as heroku-cli via Chocolately in Win10

After cloning the repo, this error happens when running image produced via heroku container:push and heroku container:release

I've seen this as well. It stems from developing between Windows and Linux. I think there are two problems:

• the start-xvfb-nginx.sh file permissions (it needs the "+x" set)
• the start-xvfb-nginx.sh line endings need to be "LF", not "CRLF" as Windows likes.

I think I have this fixed by modifying the Dockerfile as such:

...
ADD start-xvfb-nginx.sh /usr/local/bin/start-xvfb-nginx.sh
RUN chmod +x /usr/local/bin/start-xvfb-nginx.sh
...

And by ensuring the start-xvfb-nginx.sh is checked out with "LF" line endings before building the Docker image.
