Ensure pre-production Drupal deployments use the corresponding data environment

[mfisher87]

This code:

snow-today-webapp/src/constants/dataServer.ts

Lines 5 to 7 in f4da298

	if (window.location.port === "8080") {
	return `${window.location.protocol}//${window.location.hostname}`;
	}

... handles selecting the correct data for the given environment IFF we're running in a docker-compose style deployment.

However, we also deploy to pre-production Drupal environments as an NPM package, in which case the default production data URL is used. We should be able to detect that we're in an integration.*.nsidc.org URL and select the corresponding pre-production data URL, e.g. https://integration.nsidc.org/api/snow-today.
