Temporarily removes Content-Type header from GET requests (#57)

Addresses an issue where the API server rejects GET requests
containing a 'Content-Type: application/json' header.

This is a temporary workaround to ensure compatibility with the
current stac-react implementation and the API server's
requirements.  Once stac-react is updated to handle headers
correctly, this workaround will be removed.

+// Currently, stac-react adds a 'Content-Type: application/json' header to all
+// requests, including GET requests. However, the api server rejects GET
+// requests with this header. Ideally, the server should accept this header, but
+// as a workaround, we remove it from GET requests to avoid server errors. This
+// is a temporary fix is just to get things working while stac-react is updated.
+// I promise it is temporary!
