[FEAT]: github_app data source should obtain the app installation ID

[scott-doyland-burrows]

Describe the need

https://registry.terraform.io/providers/integrations/github/latest/docs/data-sources/app

This data source only retrieves:

id, name, node_id, slug.

Can it be updated to also retrieve the app installation ID.

This is needed because other resources, such as below, require the installation ID passed to them:

https://registry.terraform.io/providers/integrations/github/latest/docs/resources/app_installation_repository

@scott-doyland-burrows that's not how the GitHub REST API works, there isn't an endpoint to lookup app installations without using the app token. We could look at introducing a github_organization_app_installations data source which would allow you to get at the same data.

Also the current github_app data source should be extended to include client_id & permissions
