Add permissions in the in-cluster RBAC doc

[tnorris]

Clusterlint is rad, while trying to deploy it at work, I ran into API permission errors. Someone else might be trying to do this, so here's a docfix 😄

This patch does three things:

• Add missing permissions for what seems like newer checks and API Groups
• Sorts the list of permissions
• Changes the RoleBinding to a ClusterRoleBinding so permissions can be picked up by the ServiceAccount

Hi @sundowndev, sorry for the ping, but you're someone that touched the RBAC docs. Do you mind taking a look at this? 😃
