feat: add `github_enterprise_actions_runner_group`

[bradam12]

Resolves #1482

This adds a new resource github_enterprise_actions_runner_group to control runner groups at the enterprise level.

Additional attribute database_id added to data.github_enterprise and resource.github_enterprise_organization. The id fields on these two items are the node ID used for v4, and the "traditional" ID is exposed via DatabaseId. Other items use node_id and id, but I didn't want to introduce a breaking change so I just added as new attributes.

data "github_enterprise" "enterprise" {
  slug = "my-enterprise"
}

resource "github_enterprise_organization" "enterprise_organization" {
  enterprise_id = data.github_enterprise.enterprise.id
  name          = "my-organization"
  billing_email = "octocat@octo.cat"
  admin_logins  = ["octocat"]
}

resource "github_enterprise_actions_runner_group" "example" {
  name                       = "my-awesome-runner-group"
  enterprise_slug            = data.github_enterprise.enterprise.slug
  allows_public_repositories = true
  visibility                 = "selected"
  selected_organization_ids  = [github_enterprise_organization.enterprise_organization.database_id]
  restricted_to_workflows    = true
  selected_workflows         = ["my-organization/my-repo/.github/workflows/cool-workflow.yaml@refs/tags/v1"]
}

Tests are added and running successfully. I set the following env vars: GITHUB_ORGANIZATION, GITHUB_BASE_URL, GITHUB_TOKEN, ENTERPRISE_ACCOUNT, ENTERPRISE_SLUG
