fix: trigger activate event when app is activated via app switcher (#23727)

When application is activated thru macOS app switcher (cmd+tab) the
App's activate event is note emitted. The reason is that
`applicationShouldHandleReopen:hasVisibleWindows:` is sent only when app
is activated via Dock. Using `applicationDidBecomeActive:` is handling
all cases properly.
