Description

• Revises data structure for lesson procedures

Caveats

• When using steps numbering, the first item in the "step" should be a rich text block (or similarly narrow block), otherwise the number will be covered up by wider media blocks.

Instructions to test

1. make vue-storybook
2. View the PageEduLessonDetail story

When using steps numbering, the first item in the "step" should be a rich text block (or similarly narrow block), otherwise the number will be covered up by wider media blocks.

@kimorr @otalutz Do you think this will be an acceptable limitation? Will most steps start with text?

Headings at levels larger than 4 look pretty funky due to the baselines of the number and the heading being far apart, but most likely and heading within one of these steps should be an H4, since "Procedures" is an H2 and procedure section headings would be H3.

This is working pretty well for me! Just a couple needed changes in the stories, I think.

Made the changes! Forgot to do a lot of cleanup before opening the PR 🤦 thanks for the review!
