Add tabs to the "Default groups and permissions" section for different instance creation dates

[Ralph Maalouf]

I created a new Atlassian cloud instance yesterday and I noticed that the groups that were created don't match the documentation here.

https://confluence.atlassian.com/cloud/create-and-update-groups-744721627.html

The default groups that exist in my newly created instance are:

• administrators
• confluence-users
• jira-administrators
• jira-software-users
• site-admins

Missing groups are:

• jira-users
• developers

Although the "Default groups and permissions" section contains a note saying "Depending on when you created your site, there might be slight differences in your site’s default groups.", and the table provides some updates for the different creation dates, I think the section would benefit greatly from having different tabs instead of combining everything in the same table. For example one tab would be named something like "before February 2014", and another would be "current".

Additional possible inconsistencies between the documentation and my newly created instance:

For the "administrators" group, the default permissions column says "a member of the 'Administrators' project role, which allows members to edit project versions and manage project content (delete issues, comments, manage watchers)."

I'm assuming that this refers to the "administrators" group being added as a default member in the "Administrators" project role, in the following Jira administration page: 

https://<site_name>.atlassian.net/secure/project/ViewDefaultProjectRoleActors.jspa

However this no longer seems to be true for newly created cloud instances: there are no "Default Groups" added for the Administrator role.
