Github actions for testing the next / master branch

    feat(ci): added github workflow for testing
    
    this will be run against pull requests on next
    and master.
    
    this also updates karma to v6 and utilizes the new
    public api so we no longer have to fork a child
    process to avoid karma < 6's behavior of calling
    process.exit(#)
    
    this also increases the default timeout of the
    integration tests as 5 seconds was just too short
    for the CI to be able to properly complete.
