Currently epel repo configs are using releasever which is set to 9.
This is causing dnf failures looking for a repo which doesn't exist.
We need to force releasever to 8 in order to install chromium needed for
the gating tests.

npm 7+ fails to install chrome-remote-interface because the package.json
dependencies do not work with newer version of npm. This is not needed
to run the tests so we move package.json out of the way before running
npm install of chrome-remote-interface.
This is blocking the resolution of the testZoomSpeedControls issue.
