Is __resources nessesary?

[Kostov6]

What would you like to be added:
Right now referenced images are added in __resources

docforge/pkg/workers/document/document_worker.go

Lines 234 to 238 in 9834a5e

	// download urls from referenced repositories
	downloadResourceName := DownloadURLName(*resourceURL)
	if err = d.downloader.Schedule(link, downloadResourceName, source); err != nil {
	return link, err
	}

But with #358 we can download them via that mechanism

docforge/pkg/workers/document/document_worker.go

Lines 156 to 170 in 9834a5e

	func (d *Worker) processSource(ctx context.Context, sourceType string, source string, nodePath string) (*docContent, error) {
	var dc *docContent
	content, err := d.repositoryhosts.Read(ctx, source)
	if err != nil {
	return nil, fmt.Errorf("reading %s %s from node %s failed: %w", sourceType, source, nodePath, err)
	}
	dc = &docContent{docCnt: content, docURI: source}
	if strings.HasSuffix(source, ".md") {
	dc.docAst, err = markdown.Parse(d.markdown, content)
	if err != nil {
	return nil, fmt.Errorf("fail to parse %s %s from node %s: %w", sourceType, source, nodePath, err)
	}
	}
	return dc, nil
	}

docforge/pkg/workers/document/document_worker.go

Lines 144 to 151 in 9834a5e

	if strings.HasSuffix(cnt.docURI, ".md") {
	rnd := markdown.NewLinkModifierRenderer(markdown.WithLinkResolver(lrt.resolveLink))
	if err := rnd.Render(b, cnt.docCnt, cnt.docAst); err != nil {
	return err
	}
	} else {
	b.Write(cnt.docCnt)
	}

With this we can also drop resourcedownloader package

Why is this needed / describe a real-world scenario:
It does not seem there is a universal place for resources. For example:

• https://docs.docker.com/get-started/docker-concepts/the-basics/what-is-a-container/ has a image with a path where images is not a root folder https://docs.docker.com/get-started/docker-concepts/the-basics/images/search-the-docker-image.webp
• https://www.cncf.io/blog/2024/12/30/cilium-releases-2024-annual-report/ has an image with url https://www.cncf.io/wp-content/uploads/2024/12/Copy-of-Single-Card-2.jpg
