[expo-zustand-styled-components]: Fix Milestone for Issues and pull requests tab for single repo

[hdJerry]

Currently milestones filter doesn't work by targeting the ID of the milestone.

Apparently, we can't filter by milestones for pull requests with the Graphql API so, you will need to extend the API by using the REST API version for that situation

Fix

• replace milestone with milestoneNumber in the query
• replace the id of the milestone with the number of the milestone
