[Guide] Using Flatpak version of CopyQ

[zoenglinghou]

I use the Flatpak version of CopyQ, and to make it work with the extension, I wrote the following shell script named copyq and put it in my PATH:

#!/bin/bash
flatpak run com.github.hluk.copyq "$@"

Since copyq command is not directly available as a CLI command, we need such a wrapper.
