Is your feature request related to a problem? Please describe.

#2398 and #2396 were great additions to templates. However, new users would have no idea what they look like; in addition, the appearance in our docs is inconsistent as we have quick netlify deploy links for default and minimal for not these two

Describe the solution you'd like

• [ ] Add example repos to host (seems to be a prereq for the deploy buttons, see markbind-init-typical repo)
• [ ] Add netlify deploy buttons
• [ ] Add some way to the documentation (link, modal, screenshot idk) to preview these template websites -- #2471 is the dedicated issue for this
