1. Allows for selecting a custom path or the default (Documents) path for saving backups. The selection is passed from the "turn-on-scheduled-backups" dialog to "BackupService". 2. After pressing the "Choose" button in the dialog, a filepicker will appear so that a folder can be selected. 3. Once the dialog is confirmed, the absolute path is saved to a pref called "browser.backup.location" and saved in the service state. Other changes: - Added the Documents folder as the default save location - Added an onUpdate function for "browser.backup.location" that passes the updated BackupService state to registered widgets (backup settings section, dialogs) - Added Storybook entries and tests for the newly updated input and filepicker Figma: https://www.figma.com/design/vNbX4c0ws0L1qr0mxpKvsW/Fx-Backup?node-id=147-4568&t=tILUMKfg8c6Ed1Ul-0 (turn on backup dialog) Differential Revision: https://phabricator.services.mozilla.com/D210850
