chore: bump version to 4.11.98 [skip ci]

- Implemented ShareRoomPicker component to allow users to pick a room for sharing content received from Android intents.
- Integrated search functionality to filter rooms and directs.
- Added virtualized list for efficient rendering of room options.
- Created utility functions for handling Android share payloads, including fetching and clearing pending shares.
