[Bug] HTTP Error 404 on website.js

Installation command works fine, however on run of say `ddoc https://deno.land/x/dash@2.2.2/mod.ts` it errors with a 404 error when attempting to get the file `https://deno.land/x/ddoc@0.0.2/website.js`.


Start by reproducing the issue with `ddoc https://deno.land/x/dash@2.2.2/mod.ts` and inspect how the CLI requests `https://deno.land/x/ddoc@0.0.2/website.js`. Trace the request for website.js and verify the command completes without a 404 while generating the documentation.
