React & Redux group project - Space Travelers' Hub

[RitaDee]

In this PR, I implemented the following:

-Fetch data and update the Redux store.

• Upon the first render fetch data from the SpaceX API endpoints:
  • Missions: https://api.spacexdata.com/v3/missions
• Once the data are fetched, dispatch an action to store the selected data in the Redux store:
  • Missions:
    • mission_id
    • mission_name
    • description
      • Use useSelector() Redux Hook to select the state slices and render lists of missions in corresponding routes.

• Display missions section lists current missions, their brief description, and participation status.
• There is also a button next to each mission that allows users to join the selected mission or leave the mission the user joined earlier.
