Terraform Configuration Files

resource "grafana_team" "test-team" {
  name  = "..."
  email = "..."
  members  = [
    ...
  ]
  preferences {
    home_dashboard_uid = null
    theme              = null
    timezone           = "Europe/Madrid"
    week_start         = null
  }
}

Expected Behavior

Terraform should be able to support the timezone as is already supported in the web interface.

The REST API also supports it, even if the documentation says it is not:

timezone - One of: utc, browser, or an empty string for the default
https://grafana.com/docs/grafana-cloud/developer-resources/api-reference/http-api/team/#update-team-preferences

❯ curl -H "Authorization: Bearer $GRAFANA_AUTH" \ 
    -H 'Content-Type: application/json' \
    -X PUT \
    -d '{"timezone": "Europe/Madrid"}' \
    "https://xxx.grafana.net/api/teams/2/preferences"
{"message":"Preferences updated"}

❯ curl -s -H "Authorization: Bearer $GRAFANA_AUTH" \
    "https://xxx.grafana.net/api/teams/2/preferences"

Actual Behavior

│ Error: expected preferences.0.timezone to be one of ["utc" "browser" ""], got Europe/Madrid
│ 
│   with grafana_team.test-team,
│   on main.tf line 30, in resource "grafana_team" "test-team":
│   30:     timezone           = "Europe/Madrid"

Steps to Reproduce

1. create a resource grafana_team
2. in preferences, define timezone Europe/Madrid
3. terraform plan

Validation happens here:

https://github.com/grafana/terraform-provider-grafana/blob/58cbf86/internal/resources/grafana/resource_team.go#L121-L127

We should probably decide whether we want client side validation or just leave it open as a string.
