Embedded GitHub status badges are not displayed

[marc1404]

Example page: https://gardener.cloud/docs/gardenctl-v2/

Wherever repository pages use a GitHub status badge, it is not displayed when embedded into the documentation.

Checking the source for such a status badge shows that the following URL is used:
https://github.com/gardener/gardenctl-v2/actions/workflows/non-release.yaml?query=branch%3Amaster

Unfortunately, on the rendered documentation page, this URL suddenly looks like this:
https://github.com/gardener/gardenctl-v2/raw/workflows/non-release.yaml/badge.svg

Somewhere during the build process (probably through Docforge) this URL is rewritten and broken.

The culprit seems to be the RawURL function in pkg/registry/repositoryhost/resource_url.go:

https://github.com/gardener/docforge/blob/5e212bfaf9df787fd8a144249b50e8b1ce070fd2/pkg/registry/repositoryhost/resource_url.go#L34

It returns a raw URL not only for blobs, but also for actions. This is what's happening with the badge URLs.

@Kostov6 How about making it explicit that raw URLs should only be returned for resources of the type "blob":

func RawURL(resourceURL string) (string, error) {
	r, err := new(resourceURL)
	if err != nil {
		return "", err
	}
	if r.resourceType != "blob" {
		return resourceURL, nil
	}
	return link.Build("https://", r.host, r.owner, r.repo, "raw", r.ref, r.resourcePath)
}

I tested the change locally, and it seemed to fix the problem. @Kostov6 If the approach looks good to you, I can open a PR in the Docforge repo ;)
