DS - Add useMemo and useCallback to useSnackbar hook

[narin]

Description

As part of the Snackbar implementation, the Mobile Feature Support team reported that they needed to patch our useSnackbar hook for usage in the app. They specifically ran into issues when a Snackbar was shown, and then hidden due to navigation change. They mentioned that issue is likely because Snackbar was being called as part of a useEffect on one of the app screens and thus had to be included in the useEffect dependency array, and this caused some side effects without the memoization of useSnackbar

Acceptance Criteria

• Examine the updates in the patch that was created
• Apply the changes in the patch to useSnackbar if they make sense
• Test in Storybook and within the app
