Examples in README.md fail

The following example [https://github.com/fivetran/prefect-fivetran#write-and-run-a-flow](url) doesn't work because it's any async call and inside a standard function. As a newbie, I was expecting to be able to copy the example and run it with my own credentials but was left with errors that were beyond my initial comprehension. After a lot of searching and learning, I have come to the conclusion that example is invalid given this is an async function.

For future newbies, it would be great to have a working examples in the documentation. I hope this helps in some way. Thanks!
