[CE/SP] Remove non-production dependencies (#33949)

Some non-production dependencies were bundled in the CE and SP images:
- `lint` was pulled as production dependency by `eslint-plugin`. Moving to peer-dependency, which is the usual strategy, addresses the issue.
- Yarn cache wasn't purged. By adding `/usr/local/share/.cache/yarn` to the mounts we ensure it's also cleaned.
