clicking on the repo <span> on the front page takes one to the external site

I guess whether this is a bug, improvement, or WONTFIX depends on whether one thinks of sourcebot as merely a "fancy bookmarking" system, and the end user really wants to navigate to the code hosting site, or whether one thinks of sourcebot as "references as a service" and thus clicks should mostly navigate to other sourcebot URLs unless otherwise designated

1. Navigate to https://demo.sourcebot.dev/
2. Observe the commaai/openpilot in the (ahem) horizontal scroll list
3. Click on it, expecting to be taken to https://demo.sourcebot.dev/search?query=repo%3Acommaai%2Fopenpilot
4. 😢 Instead observe that one is taken to https://github.com/commaai/openpilot
