Team3 [4pt] Fetch dragons - Fetch data

[ClaudiaRojasSoto]

Fetch data from the Dragons endpoint (https://api.spacexdata.com/v3/dragons) when a user navigates to the Dragons section.

Once the data are fetched, dispatch an action to store the selected data in Redux store:

• id
• name
• type
• flickr_images

NOTE: Make sure you only dispatch those actions once and do not add data to store on every re-render (i.e. when changing views / using navigation).
