Permissions updates

We've made a couple improvements to admin permissions in Canny. 
New permission: View user details
The Users tab in Canny contains personally identifiable information (PII) like email addresses. This permission allows you to specify which admins should have access to that information.
Permission update: "Manage teammates" is now free
Some teams have IT people who are responsible for managing admins in Canny. They do not use any Canny functionality. Therefore, we have made the "Manage teammates" permission free so these admins don't count as a paid seat.
Admin roles are available on Canny Growth and above.
