Remove “Unlink from Group”

Hi @nouveatopia-

So I’m tracing the logic from the templates to the function that creates the action links:
https://github.com/boonebgorges/buddypress-docs/blob/master/includes/templatetags.php#L1191

The Groups unlink action link is added to that list via a filter, too:
https://github.com/boonebgorges/buddypress-docs/blob/master/includes/integration-groups.php#L73

When I look at the logic:
https://github.com/boonebgorges/buddypress-docs/blob/master/includes/integration-groups.php#L845

It looks to me like the thing to filter is actually whether or not the current user can do the capability bp_docs_dissociate_from_group. By design, only site admins and group mods or admins can disassociate a doc: https://github.com/boonebgorges/buddypress-docs/blob/master/includes/integration-groups.php#L1918

If you want to only allow site admins to do that, it’s probably easiest to filter the capability, something like this should work: https://gist.github.com/dcavins/e7a3a75db2da898cf66b9d7c65363a71
