[Feature] Text component: Update stories

[narin]

Description of Change

Update Text component storybook stories:

• Update doc url
• Conditionally hide tone and size props when variant is 'display'
• Hide 'error' tone option in Heading story.
  • Note: Storybook only allows for 1 condition per control at the root level. Since I set the tone to be conditionally hidden for the display variant, I could not add another condition to hide the error option for tone when the variant is heading. Because of this, the error tone is only hidden on the Heading story and will still be visible if switching variants on the Docs page or other stories.

Also updates a missed requirement: bottomSpacing should only be fully customizable for Heading and Display variants. For Body, bottomSpacing should only be able to set to 'none' or left undefined to use the default.
