Deno doc inserts incorrect links in html

[nikelborm]

I have this repo with reproduction:
https://github.com/nikelborm/deno_docs-repro-1

all_symbols page works properly	main root page also works as expected

All pages from non-default module work properly	Pages under default module break

On this page links to styles are broken, as well as cool_docs link on the screenshot

This seems to be very trivial issue to fix, because you can just replace all ../ with ../../ and it's enough:

cd docs

find ./index -type f -exec sed -i 's_\.\./_../../_g' {} +
find ./index -type f -exec sed -i 's_\.\./_../../_g' {} +

I think this is the same as #685 [deno doc --html generating incorrect url reference in subpages]?
