LGTM, thanks for removing this complexity from MWs Janki! 🎉
I left a couple of nit comments

[joana-cps]

Should we also update this banner in the rule creation page?

Any suggestion for the new text @nastasha-solomon @joana-cps ? Maybe just

Maintenance windows are running.
Rule notifications are stopped while maintenance windows are running.

?

Some suggestions:

Maintenance Window in Progress
Rule notifications are currently paused due to an active maintenance window. Notifications will resume automatically once the maintenance period is over.

Ongoing Maintenance Window
Notifications are paused while the maintenance window is active.

Note that we aim to enhance the way we display this type of message to make it more contextual, as it currently doesn't provide exact information about which ones are affected.
