New Lesson template

[acrymble]

#972 update metadata block example, has made me realise we could simplify our author and editor guidelines quite a lot by just offering a template for people to use in new lessons. It could look like this:

title: ["YOUR TITLE HERE"]
collection: lessons
layout: lesson
slug: [LEAVE BLANK]
date: [LEAVE BLANK]
translation_date: [LEAVE BLANK]
authors:
- [FORENAME SURNAME 1]
- [FORENAME SURNAME 2, etc]
reviewers:
- [LEAVE BLANK]
editors:
- [LEAVE BLANK]
translator:
- [FORENAME SURNAME 1]
translation-editor:
- [LEAVE BLANK]
translation-reviewer:
- [LEAVE BLANK]
original: [LEAVE BLANK]
review-ticket: [LEAVE BLANK]
difficulty: [LEAVE BLANK]
activity: [LEAVE BLANK]
topics: [LEAVE BLANK]
abstract: [LEAVE BLANK]

maybe worth having a live preview link on the main site so they can also see what each of these looks like when rendered.

Good idea! I second the template and yes we need to keep updated the examples found in our guidelines. For tanslations though, we need a original field. See here:
