This PR removes all CMS code from the `www` app. This includes fetching
of blog posts, API routes for proxying blog posts and types.
All functionality should remain the same (and the number of blog posts
should be the same).

## What kind of change does this PR introduce?
Frontmatter name change.
## What is the current behavior?
We repeatedly mistake `thumb` for `image` and visa versa, meaning the
wrong images are used for Open Graph and in-site thumbnails on blog
posts. Events and case studies use the same naming convention too.
## What is the new behavior?
These two bits of frontmatter are renamed for clarity:
- Blog posts: `imgThumb` + `imgSocial`
That mapping for blog posts:
- `thumb` is now `imgThumb`
- `image` is now `imgSocial`
These related bits remain as-is:
- Events
- Case studies
The
[www/README.md](https://github.com/supabase/supabase/blob/dnywh/chore/blog-image-frontmatter/apps/www/README.md#best-practices)
file has been expanded to clarify all of the above. It now also provides
instructions on image optimisation.
## To test
A lot of files were touched here. Please help make sure:
- [ ] The CMS works as intended. This is the **biggest unknown**.
- [x] All blog posts render the correct image as their on-site thumbnail
and Open Graph image. You can test the latter by firing up a draft
iMessage. Online Open Graph services like Facebook cache images, so
aren’t reliable.
- [x] All events render their correct images
- [x] All case studies render their correct images
- [x] All customer stories render their correct images ([known
