Feature Error Message

[SallyMcGrath]

Show an error message

Instructions:

Display an error message in <Bookings /> if there is an HTTP error when fetching data from the server. To test this, try loading data from https://cyf-react.glitch.me/error, which will return a 500 HTTP error.

Hint: Try looking at your Pokemon app for an example.

If you complete #22 and merge it, you will likely reduce the work needed here

Test:

• When loading bookings data from the /error endpoint, an error message should be displayed on the screen.
