WPZ-2: Adding instant search

[ambrose40]

Estimated time: 1 hour

Requirements

As a user, I want to see book results as I am typing in the search field -- I don't want to have to submit the form.

• Starting from the chore/code-review branch from Task 1, create a new branch feat/instant-search.
• Update the code to provide instant search results as the user is typing.
• Be sure not to spam the API with too many calls -- no more than one request every 500 ms.
• Open the e2e test file apps/okreads-e2e/src/specs/search-books.spec.ts. Enable the second spec by renaming xit to it, then implement the test to ensure instant search works.
• Commit your changes to the feature branch
• Open a pull-request with chore/code-review as the target.
