Docs: Fix broken and incomplete storybook stories

[francinelucca]

Summary

Saw some broken stories in our docs/storybooks, some examples:

• https://primer.style/foundations/primitives/typography#weight
• https://primer.style/primitives/storybook/?path=/story/color-transparent--light&globals=theme:light
• https://primer.style/foundations/primitives/typography#font-shorthand

And some stories with missing information (mainly source value):

• https://primer.style/foundations/primitives/size
• https://primer.style/foundations/primitives/typography
  -https://primer.style/foundations/typography

Looks like at some point the .json info files renamed property from value to $value, adjusting stories to reflect that.

List of notable changes:

• Map all instances of ...original.value to ...original.$value in storybook stories that pull data from docs/**/.json files
• Map to description instead of comment in Typography Functional Overview story.

What should reviewers focus on?

• All stories should be able to render and have source values

Steps to test:

1. Open the preview documentation that has been deployed in this pull request
2. Verify token stories correctly display source value and that previously listed "broken" stories are now able to render
