👷(ci) fix symlink to Cunningham when turbo cache is on

Had the situation where the symlink to the cunningham bin was not
created on yarn build due to the fact that the tokens repo was
not updated. The turbo just replayed logs output, but doing this
prevent the symlink to be created from the package.json's build script.
So, in order to make sure that the symlink always exists, I added it
to the CI build job.
