[MAINT]: Missing distinction between roles and permissions

### Describe the need

There is currently a function in the provider called `getPermission` that is being used to convert a role (e.g. `read`) into a permission (e.g. `pull`). The validity of this should be investigated as a comparison to the GitHub REST API; for example `github_repository_team` currently has the `permission` attribute which is being mapped to the `role_name` coming back from the REST API while the `permissions` array data from the REST API are being ignored.

This is relevant to #2498.
