[expo-notifications] Fix changelog formatting (#10639)
[expo-notifications] Fix changelog formatting (#10639)

# Why

I think `expotools` may have bodged the changelog while publishing.

# How

Reformatted the changelog manually.

# Test Plan

This I don't know how to do — how to verify that `expotools` will modify the markdown file correctly?
