Test Case #2 - brave/brave-browser#27851

As per @deeppandya, we don't block users from opting into Brave Rewards when they have notifications disabled. We display the warning but a user can dismiss the modal by pressing X and continue with onboarding. So the following verifies that the user received a warning when disabling either All Brave - notifications or All "Brave Ads" notification channels from Notifications settings.

Test Case #1 - not enabling notifications via initial onboarding

• installed 1.49.82 Chromium: 110.0.5481.52
• tap on Continue under the Brave notifications make it easier onboarding
• tap on Dont allow under the `All Brave - Nightly to send you notifications?" modal
• tap on the rewards panel and select a country via the Select your country panel
• tapping on Continue should display the Enable notifications from Brave to earn Brave Rewards modal
  • ensured that tapping X dismisses the modal and you can still run/setup rewards via the panel
  • ensured that tapping on Open Settings opens Notifications under Settings
