refactor: Remove buildjet cache from cache-build action (#26181)

* refactor: Remove buildjet cache from cache-build action

The buildjet cache was causing cache misses due to unstable hashFiles()
keys that included generated Prisma files. Since we now use Turbo Remote
Caching, the buildjet cache is redundant and was causing more problems
than it solved.

This simplifies the cache-build action to just run yarn build, relying
on Turbo Remote Caching for build artifact caching.
