Bumps @aragon/os from 4.2.0 to 4.2.1.

Release notes

Sourced from @aragon/os's releases.

v4.2.1

Special thanks to @​haythem96 for helping make this release possible 🎉

This is a patch release to include a new forwarding interface, IForwarderFee.

IForwarderFee: allowing forwarders to declare they require fees

IForwarderFee is an optional interface that can be implemented by Forwarders (IForwarder) to declare that their forwarding action requires a fee be paid.

This is used by frontends to assess whether a forwarding path has additional requirements to succeed:

• A "pretransaction" to approve tokens for the first forwarder requiring fees
• An ETH transfer to the first forwarder
