viewer doesnt work with folders of markdown files

Couple of examples:

- ipfs://bafybeiasi6i5sc3xxbryylarwmowdqwyzzwavkwda5yczhf7bmuhzkjgye/sample-post.md
- ipfs://bafybeicxpc74abbgf7khzqkc2eay7vmhgbsmo7bcymmvv4i3wqafnus2aa/sample-markdown.md

There doesn't seem to be any way to view this within the viewer, ends up giving a next.js 404 error
