Align use of buttons, links and their options

[julrich]

There are different definitions of buttons in our current components, and adjacent definitions like links that share a lot of component API. Different in this context means differences in their defined properties.

Those should be aligned, and respectively named differently (different use case -> different name, don't reuse buttons as a catch-all).

Some examples (buttons):

• label, icon, target:
  • Cta: https://github.com/kickstartDS/ds-agency-premium/blob/main/src/components/cta/cta.schema.json#L45-L62
  • Hero: https://github.com/kickstartDS/ds-agency-premium/blob/main/src/components/hero/hero.schema.json#L49-L66
  • Video Curtain: https://github.com/kickstartDS/ds-agency-premium/blob/main/src/components/video-curtain/video-curtain.schema.json#L37-L54
• Button Group / label, target, variant, icon, size, disabled:
  • Image Story: https://github.com/kickstartDS/ds-agency-premium/blob/main/src/components/video-curtain/video-curtain.schema.json#L37-L54
  • Section: https://github.com/kickstartDS/ds-agency-premium/blob/main/src/components/section/section.schema.json#L219-L221

Examples (links):

• icon, label, href, newTab:
  • Contact: https://github.com/kickstartDS/ds-agency-premium/blob/main/src/components/contact/contact.schema.json#L51-L90
  • Blog Author: https://github.com/kickstartDS/ds-agency-premium/blob/main/src/components/blog-author/blog-author.schema.json#L23-L25
