Fix import of map api key

What does this MR do?

Fixes a typo from !2621 (merged)

How confident are you it won't break things if deployed?

this should work

How to test

1. Add the api key to config.inc.dev.php and change the conditions for isDev in client/src/mapUtils.js to make the dev environment use the Geoapify
2. Checkout branch locally
3. Open the map
4. There should be tiles, or 401 responses from Geoapify (which is ok because of IP filtering)
