Update codeowners to use Vercel Spaces (#50841)

Move as much of codeowners as possible to use Vercel Spaces. 

1. Makes `@timneutkens @ijjk @shuding @huozhi @feedthejim` global owners
2. Make the `@vercel/next-js` team _optional_ owners of **/docs**,
**/errors**, and **/contributing**, makes team owners of a few packages
as per old config.
3. Make `@vercel/devex` (docs and devrel) owners of **/docs**,
**/errors**, and **/contributing**
4. Make `@vercel/devrel` (devrel only) owners of **/examples**
5. Make `@vercel/web-tooling` owners of specific files and folders (as
per old config)

Leaves @styfle as owner of **image** files on the old config since this
pattern `/**/*image*/** ` can't be used with Vercel Spaces.

Note: We cannot add * or / at the end of files.
