    CI: Install the stock grcov, not my branch
    
    I told github to delete my accessibility branch when it got merged...
    
    ... it got merged ...
    
    ... it got deleted ...
    
    ... and of course I forgot about it, and now the container image
    couldn't be regenerated because my branch no longer exists :)
