Readme not rendering for `std/testing`

[jespertheend]

When I visit https://deno.land/std@0.129.0/testing the readme is not visible, even though README.md is bold. Other folders with a readme seem to work fine.

Seems like std/testing is not the only page with this issue:

• https://deno.land/std
• https://deno.land/std@0.129.0/http
• https://deno.land/std@0.129.0/path

Others are still fine, https://deno.land/std@0.129.0/uuid for instance
