CI: Fix CMake definition of streaming service options

On master branch, client information for Twitch, YouTube and Restream
integration are set as CMake cache variables. The hashes can contain
otherwise "illegal" characters such as backticks which need to be
enclosed in a string, but also cannot be subject to variable
substition.

Using single quotes should fix this.
