[native] Allow user to ‘see more’ on native and navigate to a full screen gallery
Summary:
Following the designs (https://linear.app/comm/issue/DES-27/view-media-for-chat), users should be able to click "see more" to navigate from the thread settings media gallery to a full screen media gallery. Using ThreadSettingsCategoryHeader didn't allow for a title and also additional text ("see more"), so I made another component that takes an onPress and actionText. This way, we can navigate to the full screen gallery when actionText is pressed. The next diff will implement the actual full screen gallery.
Depends on D6659
