jetbrains-toolbox: Move to extras (#148)

* jetbrains-toolbox: Fix manifest

- Add description
- Use jsonpath for checkver
- Do not install. Extraction is enough
- Create default configuration file if there is none.
    - Old implementation was completely nonsense
    - It basically add install_location all the time even when that file exists.
         - So it override user setting if user wanted to change this location

Why is this manifest inside Main bucket when it is clearly GUI application with only small command line support
