Jira Server: Enhance Add/RemoveIntegrationProvider to add org-scoped Provider(s)

[jordanh]

Issue - Enhancement

The Jira Server integration is much more useful and much easier for org administrators to administer if the Provider can be configured at the Organization level. Today, the mutation (and the shape of its parameter) don't allow for this, even though the underlying data architecture does.

Acceptance Criteria (optional)

Administrators can:

• Can run a GraphQL query via the administration interface to add an org scoped Jira Server/Jira Data Center Provider
• " to remove a Jira Server/Jira Data Center Provider

Users can:

• Use the Team Settings->Integrations menu (and other interfaces) in order to add Jira Server/Jira Data Center to their team

Parabol Customer Success:

• Can refer to an internal Notion document on how to help users add their org-scoped Provider

Estimated effort: 5 points (see CONTRIBUTING.md)

This already works. An integration provider is always added to a team, but can be scoped to an org, i.e. the whole org where the team lives has access to the integration provider. See also discussion on #6014.
