Revert "ENHANCEMENT Added DPS SSL certificate for Windows, as cURL cannot verify the DPS URL (https) is valid on platforms without appropriate certificates installed."

This reverts commit 35e86d28cff6d324a1c8395a4598c9819f70dd66.
Curl/OpenSSL fails with "unable to get local issuer certificate".
Most likely the certificate is too old. Tried on Windows Server 2008,
the certificate gets checked fine with PHP curl's default settings
(CURLOPT_SSL_VERIFYPEER=true, CURLOPT_SSL_VERIFYHOST=2).
