index and setup page not linked properly

[dpshelio]

At least when online on gh-pages the index and setup pages for English are getting a 404 because jekyll is not building them as: /index/ or /setup/. This could be solved by adding permlinks to these.

Probably we need to change https://github.com/carpentries-i18n/carp-theme/blob/e7710037f29f126b5810425ccdd747f81a4a0806/_includes/navbar.html#L37 to point only to include.pathLocale and on the index.md pages for source and translated languages to have the following options:

• Source:

root: .  
permalink: index.html

• translation:

root: es
permalink: es/index.html

as index is the only page that doesn't follow the pattern /:path/index.html

Similarly for other pages:

• CoC:

• source

  root: .
  permlink: /conduct/
  

• translation

  root: es
  permlink: es/conduct/
  

  (though we need to check how we want to refer to this page: coc,conduct,code_of_conduct,...
  The "official" theme uses: CODE_OF_CONDUCT.html. However, the problem then is that the translations will become: es/CODE_OF_CONDUCT/index.html and that's harder to wire)

• Setup:

• source

  root: .
  permlink: /setup/
  

• translation

  root: es
  permlink: es/setup/
  

• License:

• source

permalink: /LICENSE/
root: .

• translation

root: es
permalink: /LICENSE/

• episodes/AIO:
• source

permalink: /aio/
permalink: /aio/index.html

• translation

permalink: es/aio/
permalink: es/aio/index.html

• extras/reference:

   root: .
   permlink: /reference/
  

  and as above for the translations...

• extras/about:

   permlink: /about/
  

• extras/design, extras/discuss, extras/exercises, extras/guide are like the above.

• extras/figures => has the link to figures/index and that one works without any change!

Switching between languages doesn't work if the files are names differently. If they're all called CODE_OF_CONDUCT and have a permalink: */conduct/ field it seems to work.
