Nested MDX paths with /index suffix fail in production

[DevinPlumb]

I was using a structure like the following in my docs.json:

// ...
      {
        "group": "Integrations",
        "pages": ["integrations/github/index"]
      },
// ...

where my file system appeared as follows:

integrations/
     └── github/
            └── index.mdx

Locally, this displayed properly and allowed me to link to the page with href="/integrations/github":

In production, the page appears broken:

Not sure which behavior is expected, but there is a discrepancy between the local development server and the production server. Could stem from how prod handles path normalization for nested index files (whereas the local development server resolves integrations/github/index to serve both /integrations/github and /integrations/github/index routes).
