chore: remove alert settings

[vinnyhoward]

Description

The "Alerts" settings section is no longer needed and needs to be removed.

I am not sure if we should remove the Alerts controller and related redux, there may be implications we don't know of when doing so. I purpose we just remove the tests, UI and possibly creating a redux migration to reset the state to default. Create a second follow up ticket to remove the controller and related redux

Related issues

Fixes: #3212

Manual testing steps

1. Goto settings page by clicking on the more icon which are the three dots in the top right corner, and then click on settings.
2. Check to see if the "Alerts" settings are gone
3. Search for "Alerts" in the settings search and make sure nothing appears other than "Security & Privacy > Security Alerts" which is unrelated to the "Alerts" section being removed
