add /skills folder to the repo and load that markdown for each skill

[jaredatron]

right now when you go to a skills page like https://curriculum.learnersguild.org/skills/Can-add-features-to-a-pre-existing-Node-codebase, you only see the skill name a link to modules that reference that skills.

User Stories

• as a curriculum editor I should be able to edit /skills/Can-add-features-to-a-pre-existing-Node-codebase.md and have that markdown displayed on the skills page
• as a user i can see "improve this page", "view on github" on the skills pages to edit the skills markdown file

Technical Nodes

• add skills markdown to the digest
• render the markdown on the skills page
• generate markdown files for each skill
• ensure the file name matches the skill slug
• ensure the "rename-skill" script moved the skill markdown file to the new skill name

Example Skill

{
  "id": "Can-use-git-fetch",
  "name": "Can use `git fetch`",
  "rawText": "Can use `git fetch`",
  "modules": [
    "Saving-Progress-With-Git-And-GitHub"
  ],
  "path": "/skills/Can-use-git-fetch",
  "contexts": [
    "Git"
  ],
  "directoryName": "Can-use-git-fetch",
  "markdownFilePath": "/skills/Can-use-git-fetch.md"
}

url: https://curriculum.learnersguild.org/skills/Can-use-git-fetch
repository file path: /skills/Can-use-git-fetch.md

/skills/Can-use-git-fetch.md

# Can use `git fetch`

Git fetch is awesome…

your generation helper script should generate a blank skill markdown file like this

# ${skill.name}

- _description tbd_

Plan of Action
1.) Create markdown files for each individual skill, as described. Make sure name matches skill id, and title matches name.
a.) Digest generates markdown file from it's own information. Id comes from the skill's id. Name comes from the skill's name.

2.) Add markdownFilePath to individual skill object.
a.) Edit digest/skills.js to include a markdownFilePath key with a value of 'skills/${id}.MD'

3.) Render the markdown file on individual skill page.
a.) Manipulate helper files to accept markdownFilePath.
b.) Put markdownFilePath into render.
c.) Fix styling.

4.) The rename-skill script should rename the skill markdown file.
a.) Figure out rename-skill script.
b.) Edit rename-skills script to function as described.
