The download button on the API docs doesn't download the Swagger OpenAPI specification; it just re-opens the docs

🐛 Describe the bug

When viewing the generated API docs, there's a rectangular Download button that promises to download the API specification. However, it just re-opens the docs in a new browser tab.

🕵️ Expected behavior

I expected to have the swagger.yml file appear in my Downloads folder.

📜 To Reproduce

1. Visit the pds-api homepage: https://nasa-pds.github.io/pds-api/
2. Click on "Specifications"
3. Pick any specification, such as "Search API v1.6.0" or "DOI API v0.2"
4. Next to "Download OpenAPI specification:" click Download
5. The download doesn't happen; instead a new tab opens with the same doc page
