Closes #42

This PR handles adding guideline resources are described in #42.

To follow the requested URL structure (comment: https://github.com/panvol/pandemic-volunteers/issues/42#issuecomment-615248137), an default locale of en is introduced and used as a scope in routes, to ensure that /en/guidelines and /guidelines route default to the same resource

Because guidelines are ephemeral, a presenter is used to display initial guidelines that have guideline categories that, in turn, have many articles. Presenters also take care of fetching and rendering metadata stored in YML files

Dimitry's TODO:

[x] add markdown parsing / rendering based on https://github.com/panvol/pandemic-volunteers/pull/44/files#diff-e55a6c615d18aeb75e0610b835b16658
[x] make methods such as GuidelineCategory.extract_slug etc., ~~metadata file fetching and loading~~(done), and loading dirs via Pathname reusable. This is because GuidelineCategory and GuidelineArticle will be sharing 90% of their methods. GuidelineArticle will also need to be able to load its own metadata
[x] move GuidelinesPresenter to app/models since GuidelineCategory is very similar and acts as a stand-in for a model
[x] add designs
