fix(GRO-655): create corepack cache dir in builder stage

Prevents ENOENT crash in migrate and seed jobs.

Root cause: corepack tries to mkdir /home/node/.cache/node/corepack/v1
but the directory does not exist in the builder stage. This was a
regression in c438f57 where the cache directory was not pre-created.
