[Refactor] - Refactor useNotification/useContext with NotificationContext

[leekahung]

Describe the Current Behavior/Feature:

Currently, the useNotification hook is simply a recalling of useContext with the NotificationContext and doesn't do anything more. It'll be simpler to just use useContext in that case. However, we could also attempt to migrate fully what we already have inside the useContext hook with NotificationContext over to useNotification. That way we can clear up some redundant coding.

Rationale:

Cleaning up codebase.

Proposed Implementation (if applicable):

For this issue, we either:

• Revert to use useContext with NotificationContext
• Migrate useContext functionality full to useNotification custom hook
