Can not run selenium test with option BROWSER=edge

[khanhcd92]

I tried with below command but it was not run

docker run -it --shm-size=2g \
            -v `pwd`/test/selenium.robot:/opt/robotframework/tests/selenium.robot:Z \
            -e BROWSER=edge \
            ppodgorsek/robot-framework:latest

An exception was thrown as below
WebDriverException: Message: unknown error: msedge failed to start: crashed. (unknown error: DevToolsActivePort file doesn't exist) (The process started from msedge location /opt/microsoft/msedge/msedge is no longer running, so msedgedriver is assuming that msedge has crashed.)

I cannot reproduce the issue, it is working fine on my computer and in the automated CI pipeline.

Which device are you using?

Could you give more information about your computer and in the automated CI pipeline ?

A 5-minute online search revealed that Amazon servers (EC2 Graviton, ARM-based) cannot run linux/amd64 images... (the image's architecture is shown on the Docker Hub)

I added explanations in the troubleshooting section of the README. (see PR #451)

I also created a separate enhancement to build and push images for multiple architectures, rather than only linux/amd64. (see #455)
