[Feature Request]: Versionated Dashboard Datasource

[Folling]

Feature Request

I would like to be able to query a specific version in the grafana_dashboard datasource.

Here's where I'm coming from:
We have two Grafana instances, one "live" and one "wip". Users are free to work on "wip" as they please. As soon as they think they've reached a presentable state, they make note of their version and submit a pull request to our Terraform configuration which has a dashboard module. This module takes in a version parameter which the user sets to their new stable version. Using this parameter, we would query the WIP's config and submit it to the "live" counterpart.

However, doing this would require the following:

data "grafana_dashboard" "wip_version" {
    uid = "myid"
    version = 12 # this field would need to be added
}
