[CmdPal] Open settings in Settings

[niels9001]

Summary of the Pull Request

This PR changes the way the user can update settings: it now opens the Settings window and navigates to the extension page. This has the following advantages:

• No window resizing of CmdPal itself, because stuff doesn't fit.
• We have a lot of other extension related settings that are not shown inline (e.g. fallback ranking, alias etc.)
• A consistent and predictable UX.
