Feature Search onSubmit

### 18. Triggering search when submitting the form

Depends on #17

**Instructions:**

Still in the `` component, add a `onSubmit` handler to the `` tag. When the form is submitted (try clicking the search button), get the value of the state `searchInput` and pass it as a parameter to the `search` prop function that has been provided for you (the `search` prop is passed from the `` component).

**Note:** Your submit handler should take an `event` parameter and add the line `event.preventDefault()` to prevent the browser from implicitly submitting the form

**Test:**

Given a searchInput field with input values entered
When the form is submitted
