feat: add group_sync and role_sync for coderd_organization_resource

[aslilac]

Group and role sync settings can now be configured as such:

resource "coderd_organization" "example" {
	group_sync {
		field = "wibble"
		regex_filter = "wib{2,}le"
		auto_create_missing = true
		mapping = {
			wibble = ["6e57187f-6543-46ab-a62c-a10065dd4314"]
		}
	}

	role_sync {
		field = "wobble"
		mapping = {
			wobble = ["wobbly"]
		}
	}
}

I don't recall if you can write to a config block (blocks can't be computed) like this. I suspect you can't.

If you can, I assume it would just be to error if the post-apply plan isn't empty.
For that you'd need to use types.ObjectValueFrom and provide it the type of the object using a map[string]attr.Type. I've got an example on the template resource & data source.
