Fix onboarding post view not being dismissed

Browse Source 
This commit fixes the issue where clicking "post" on the onboarding sheet does not dismisses itself under certain device/iOS combos.

The root cause is that the behavior of `dismiss` calls under a deeply nested view (i.e. not a direct subview of the sheet) is inconsistent depending on the device or iOS.

This fix does two things:
1. It upgrades the usage of `presentationMode` (which is deprecated) to the new `dismiss` API
2. It makes the onboarding sheet view (A direct subview of the sheet) to listen to signals from the post view and use that to also call `dismiss()`, which is explicitly supported by Apple in their docs (https://developer.apple.com/documentation/swiftui/environmentvalues/dismiss)

Testing
-------

PASS

Device: iPhone 13 mini (physical device)
iOS: 17.1
Damus: This commit (Local build, no local mods)
Setting: "Always show onboarding" is set to ON
Coverage:
1. Clicking "post" on onboarding post view publishes the post and dismisses the view. PASS
2. Clicking "cancel" on onboarding post view dismisses the view without publishing. PASS
3. Dragging the onboarding post view down dismisses the view without publishing. PASS
4. Making a normal post (I replied to a thread) still publishes the post and dismisses the normal post view sheet. PASS

Testing on other Device/iOS combos
---------------------------------

PASS

Preconditions:
- iPhone 15 Pro (simulator) on iOS 17.0.1
- iPhone SE 3rd gen (simulator) on iOS 16.4
