I would like to see the release notes for OpenTofu provider updates in the PRs. I noticed in the log output that there isn't a sourceUrl, like there is for github-actions, for example, which do have release notes in the PRs.

I have tried to add a sourceUrl to the terraform-provider datasource in packageRules using a template to construct the github URL using the packageName:

{
  "matchDatasources": [
    "terraform-provider"
    ],
    "enabled": true,
    "registryUrls": [
      "https://registry.opentofu.org"
    ],
  // sourceUrl required for release notes. This should be the URL of the provider's GitHub repository
  // Example from renovate docs https://docs.renovatebot.com/templates/#split
  // {{ lookup (split packageName '-') 1 }}
  // packageName: "hashicorp/aws" should be "hashicorp/terraform-provider-aws" for example

  "sourceUrl": "https://github.com/{{ lookup (split packageName '/') 0 }}/terraform-provider-{{ lookup (split packageName '/') 1) }}"
}

The screenshot below shows the value in the pull request (this is a private repo - so I cannot share the link. I can replicate in a public repo if required).

Is it possible to use the Template syntax to achieve this?

Please update the title/description to be like "Support template compilation for sourceUrl". I don't think this is OpenTofu-specific

[chris3ware]

I've updated the title, would this be better as an issue now?
