## PR-Codex overview

This PR addresses a `process not defined` error that occurs when using the `thirdweb/contract` import in Vite by ensuring that the `process` variable is only accessed when it is defined.

### Detailed summary

- Updated `PUBLISHED_PRIVATE_KEY` export in `packages/thirdweb/src/utils/any-evm/zksync/constants.ts` to check if `process` is defined before accessing `process.env.ZKSYNC_PUBLISHED_PRIVATE_KEY`.
