Moving away from Vercel

[maxime-rainville]

Vercel says we'll have to pay in 6 months. When Elvis was originally envision, GitHub action didn't exist.

We can probably move away from vercel and use GitHub Action+Pages instead. That will allow us to remove a redundant tool from our tech stack.

Notes

• Refer to Elvis has too many domains and none of them are good #121 for all the domains (and seemingly separate host sources) we currently have for this

Acceptance criteria

• Elvis deployment and hosting is moved to GitHub Actions and GitHub Pages.
• Elvis deployment and development doc is updated to reflect any changes to the applications.
• A something.silverstripe.org domain is configured and points to the GitHub pages.
• Vercel domain redirect to the new GitHub Pages domain (Maybe that's not worth trouble)
• Any reference to Elvis in the official dev docs or repo doc is updated to point to the new URL
• Asset page on confluence is updated
