Begin support for translations

[NullVoxPopuli]

Implementation prompted by: #901

This will enable users:

• to switch to their preferred language
• help translate to their preferred language
• not need to worry about the technical details of how to setup ember-intl

Non-goals:

• actually do translations for non-english (PRs very welcome for that)

Open for discussion:

• keep everything in git? or lean on something like CrowdIn? (or other translation service?)
  • I think CrowdIn has an embeddable widget to allow folks to translate without interacting with code
    • I can set this up and own it if folks want to see how it works / a demo, etc

Remaining Requirements:

• need to lessen the barrier to contribution / translation submission (potentially via in-site widget)
• need to have a way to display when translations are out of date on a specific page (most useful for the guides)
• need to polish up the language switcher

Developing:

• locally, there will be "missing translation" errors", but in production a fallback of english is configured

Notes on the PR:

• translation switcher needs work, what is in this PR is the bare minimum to demonstrate the functionality
• sample translations are from google translate, so, we'll see if native speakers agree with a machine or not 🙃 (not required for merging, but just demonstration in this PR)

By putting the whole list in a translation, different languages can either

• swap these with links to the same resources in a different language (maybe that's supported via query params or something),
• add language-specific resources
• replace all the links entirely

added this because the console warnings about a bunch of different ember-cli-babel versions kinda make this app look unmaitained 😅
