Issue: Unable to directly preview section (_index.md) pages

[michaeltlombardi]

Describe the bug

With a Hugo site that has section pages, which are always named _index.md and map directly to the folder they're found in, I'm unable to preview the markdown via the Open preview command in the action bar. Instead, I have to go to the site root and navigate to the page from there.

When I try to open the preview, it always appends _index to the preview path. I can set the slug value in the markdown file's metadata, but setting it to null or an empty string puts the preview path to _index and slug is also used by Hugo.

To Reproduce
Steps to reproduce the behavior:

1. With a Hugo site and the following file: content/foo/_index.md
2. Set the frontmatter.json to:

   {
     "frontMatter.framework.id": "hugo",
     "frontMatter.content.publicFolder": "static",
     "frontMatter.preview.host": "http://localhost:1313",
     "frontMatter.content.pageFolders": [
       {
         "title": "Posts",
         "path": "[[workspace]]/content/foo",
         "previewPath": "foo"
       }
     ]
   }

3. Open content/foo/_index.md
4. Start the server
5. Select the Open preview command
6. See that the preview URL is http://localhost:1313/foo/_index

Expected behavior

There should be a way to override the preview path on a per-file basis (without munging the metadata for the SSG itself) to work around this issue.

Additional context

I filed this as a bug because I can't see a way to preview section pages at all, but I do see that I'm sorta asking for a feature request here as well - I think being able to add metadata to override the Front Matter configuration on a per-file basis is likely really helpful, especially without the sort of SSG-aware configuration behavior described in #254.

Good catch, will change the behavior to ignore the _index and index paths to be applied to the URL.

@michaeltlombardi this has been fixed and is available for testing.
