Group search endpoints don't return access.

[ssilvert]

Describe the bug

When we search for groups, the returned group entities do not include the access attribute.

So the only way to see the fine-grained access is to do a GET on the single group like this:
http://localhost:8180/admin/realms/test/groups/1cc6a85b-0c4d-4911-8fb4-bc3debf4b1b4

This returns the fine-grained access attribute, which looks like this:
"access":{"view":true,"manage":true,"manageMembership":true}

But we need this information when we search as well.
