chore(build): update syncpack config (#190)

This PR updates the syncpack configuration to enforce that:

- The following versions are in sync:
  - `yarn` (`packageManager`)
  - `node` (`engines`)
  - All other dependences (`dependencies`, `peerDependencies`, ...)
- We use the `workspace:^` version of:
  - `@metamask/keyring-**` packages
  - `@metamask/eth-**-keyring` packages
