[FR] Possibility to delete past notificiations

[lxwulf]

Description

It would be really helpful to have the possibility to remove notification, specially the past ones.

Impact

At the moment, it's really annoying if you set up notifications, and after the date they still always pop up when you open AppFlowy. It would have a big impact in how AppFlowy can be used for. At the moment as example, I do not create any time-depending to-dos because of that mentioned behavior.
