Check response status for 422 in the EDS retryable data fetch function, rather than the response itself

[charparr]

In this function https://github.com/ua-snap/data-api/blob/7a11164ae1dec5d561a8c98828fd752d1d8b8d3b/routes/eds.py#L34C1-L52C1

the line with and (response.status != 400 and response.status != 404 and response != 422) should actually have response.status != 422 as the last term.

As written, the consequence is that we may not be sleeping before retrying the request.
