Run tests on Grafana 11.6.0

[alexander-akhmetov]

Many tests broke on 11.6.0, listing them per team using this table. Changes are split it separate commits since in this way it's a bit easier to test them in the CI with the newer Grafana version.

Team-specific changes

@grafana/dataviz-squad

• For grafana_library_panel resource, folder_uid was populated with a migration in Grafana > 11.0.0 so I added it to the TF files with the required versions.

---

@grafana/access-squad

• TestAccDatasourceRole_basic failed with Failed to create role: role with the provided name already exists: Changed ParallelTest to Test to fix role creation conflicts, but it's unclear why it broke after the version upgrade.

• TestAccFolder_createFromDifferentRoles: Skipped for Grafana 11.5.0+ due to permission model changes (ref: AuthZ service: Take action sets into account when checking folder create permissions grafana#98751).

@grafana/access-squad Could you please check these and help with a proper fix?

@grafana/sharing-squad

• TestAccPlaylist_basic (grafana_playlist)
  • Changed this test and other playlist APIs the require Grafana <= 11.0.0. The API returns k8s-style responses now and the tests fail.

@grafana/sharing-squad I added <= 11.0.0 for now, but I am not sure what is the right fix here.

In order to lower resource usage and have a faster runtime, PRs will not run Cloud tests automatically.
To do so, a Grafana Labs employee must trigger the cloud acceptance tests workflow manually.
