fix(docs): add version to style guide redirects

[jahn-junior]

• Have you updated CHANGELOG.md with relevant non-documentation file changes?
• Have you updated the documentation for this change?

---

The current docs redirects specify an absolute path with no version, resulting in a 404 (example).

I'm not familiar with sphinx-reredirects, but this isn't ideal. We're mixing Sphinx and RTD concerns. Nothing in the slug should be reflected in redirects.

If we can't find a workaround, I think we should instead switch to rediraffe. It should be quick to set up.

[akcano]

I concur. Next thing you know, we switch to stable, then something else, there will be no end to it.

You can use /page/ to indicate the default version. It doesn't work with subprojects - but it does for anything on rtd-hosted or it's own domain.

'reference/style-guide/': '/page/reference/rst-syntax-reference',

For instance: https://canonical-starter-pack.readthedocs-hosted.com/page/tutorial/

You should be able to use relative paths in the redirect to fix the path without specifying an RTD version. I'll suggest it.

[minaelee]

Try it this way.

Can confirm this works.
