Fix certificates Studio page sidebar Help text

Description

Currently says that course team members with Admin privileges can activate certificates. There has been a change: only edX staff can activate certificates.

Acceptance criteria:
The Studio sidebar text (edx-platform > cms > templates > certificates.html) is updated so that the sentence: "To begin issuing certificates, a course team member with the Admin role selects Activate." is replaced with these 2 sentences:
"After you have configured and previewed your certificate, ask your edX partner manager to activate your certificate. When your certificate has been activated, you can begin issuing certificates to learners."
