Redirect to story/canvas from non-existent docs page

[ArrayKnight]

Describe the bug
Introducing docs addon leads to poor UX when switching between docs pages and stories without docs pages.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://storybook-addon-headless.netlify.com/
2. Notice that the default page is a docs only page and that the path is a story, not docs
3. Notice that the paths for the 3 docs pages are not stories, but docs instead
4. Click on Examples > GraphQL > Artworks (a story without docs)
5. Notice that the story loads as expected and that the path is a story, not docs
6. Click on any of the 3 docs pages
7. Click on Examples > GraphQL > Artworks
8. Notice that the story doesn't load as expected and that the path is docs, not story

The bug is that there's no value in showing a docs page that doesn't exist and that there's no way (that I'm aware of) to control the navigation links.

Expected behavior
Any (or all) of the below:

• The docs page redirects to the story
• The sidebar navigation links should always point to the story path
• Docs only pages should default to using the story path (only)

@ArrayKnight What a cool addon! Why don't you try the viewMode parameter, available in 6.0.0: #9090

Once v6 is released/stable I'll give that a shot. Is there no way to do so in v5?
