nomad_job data source documentation doesn't match attributes from actual implementation

[MatthewJohn]

The documentation for the "nomad_job" data source is quite incorrect:

• https://registry.terraform.io/providers/hashicorp/nomad/latest/docs/data-sources/job#desired_total suggests that task_groups.desired total should exist.
• https://github.com/hashicorp/terraform-provider-nomad/blob/main/nomad/datasource_nomad_job.go#L103 task groups schema is generated using taskGroupSchema()
• taskGroupSchema() does not contain this attribute: https://github.com/hashicorp/terraform-provider-nomad/blob/main/nomad/resource_job.go#L240

Looking at the documentation, this attribute was added in d07fdf6, which was first included in v1.3.0. But even that release doesn't contain these attributes: https://github.com/hashicorp/terraform-provider-nomad/blob/v1.3.0/nomad/datasource_nomad_job.go#L98

Is it all updated automatically using tfplugindocs, or does it need updating manually? If the former, I'd be happy to update and create a PR

(I didn't include any the Github issue template, as this isn't a bug that needs reproducing, so logs, code etc didn't seem applicable)

I also wonder if it's possible to rename the data source file, since it doesn't match the standard conversion for terraform providers (which is used by nearly all of the others in this provider): datasource_nomad_job.go -> data_source_job.go
