Add options to use a .jsonc extension for the config filename

[yonatan8070]

This is to allow text editors such as Visual Studio Code to recognize that the file is a JSON file and add syntax highlighting accordingly

The proper format is jsonc for json with comment.

Fixed it

Thanks!

PR title and commit message still say json. Should read jsonc. Just a mention so it's kept in mind when it comes to release notes.

@yonatan8070 I noticed that man waybar shows this:

DESCRIPTION
       The configuration uses the JSON file format and is named config.

       Valid locations for this file are:

       •   $XDG_CONFIG_HOME/waybar/config
       •   ~/.config/waybar/config
       •   ~/waybar/config
       •   /etc/xdg/waybar/config
       •   /etc/xdg/waybar/config

Would it be appropriate to mention that all of those are also valid with a .jsonc extension?
