Add information to the recovery page

Adds error & environment information to the recovery page when
available. The info will be displayed when the error boundary catches an error only.

Otherwise, does a few minor tweaks to the UI of the page.

- Add DevPage button to throw an uncaught error to go into recovery
- Add "Delete Save" button in recovery from Game Options (refactored into its own
component)
- Use "Soft Reset" button from Game Options (refactored into its own
component)
- The "Soft Reset" & "Delete Save" buttons now have confirmations
- Add tooltip on "Disable Recovery Mode" button
- Add timestamp to the RECOVERY.json filename
- Add textarea containing markdown with the current error details, if
available
  - Error
  - Page
  - Version
  - Environment
  - Platform
  - UserAgent
  - Features
  - Source
  - Stack Trace
- Change GitHub new issue link to contain default body & title, if possible
- Change links to not take the full width (they were clickable by mistake)
- Fix "Disable Recovery Mode" not resetting the ErrorBoundary's state,
making going back to terminal impossible
