Fix follow button on browse testimony page

[LauraUmana]

Issue: #1621

The changes I made were:

1. Added an event prevent default so it would no longer navigate to the next page
2. I had to add a context to the follow button so I can bring state up.
3. I also changed the queryResult of the useEffect in FollowButton.tsx to an object instead of a string. This way it can house all of the orgs I'm following and not following.

Checklist

• [ x] On the frontend, I've made my strings translate-able.

This is a great start! I just had a few comments:

• One thing to note is that the FollowButton component is also being used to follow Bills on each Bill Detail Page with the FollowBillButton component in the same file.
  • As a result, the Follow button doesn't work on the Bill Detail page, which I assume is because the Context Provider is being applied only for TestimonySearch, which does not cover the Bill Detail page.
  • A solution could be that we could move the Provider higher up the component tree so that both the Bill Detail Page and the Testimony Search are included in the provider.
• There are also a few formatting errors (i.e. spacing)
