Update (Prerequisites) Dependencies

[tweidinger]

As the new version of Tauri will be replacing dependencies with newer versions and remove others, we need to update it in all places of our documentation. First we should start with prerequisites instructions and then search for other places.

• webkit2gtk 4.1 to 6.x
• Removal of libappindicator
• Addition of freedesktop/ksni relevant dependencies (Need to figure out specifics first)
• TBD
