Installation instruction for RockyLinux 8 (EL8)

<!-- Feel free to change the order of sections if appropriate. --> Thanks a lot for the great gpustat tool! I'm trying to integrate this into my Slurm cluster monitoring tools. Could you kindly add instructions for RockyLinux 8.10 (and other RHEL 8 clones)? On our systems working installation instructions seem to be: ``` # dnf install gcc python3-devel # pip3 install setuptools-scm # pip3 install gpustat ``` Here is what happens with the current installation instructions: ``` # pip install gpustat -bash: pip: command not found ``` On EL8 one must use pip3 in stead: ``` # pip3 install gpustat WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.
