fix(contracts-sdk): move the older multiformats dependency from peerD…

[Ansonhkg]

Wrong version of multiformats package breaking @lit-protocol/contracts-sdk #403

Description

#403

The multiformats package is only used in the contracts-sdk, so this issue wouldn't affect any other packages. It's currently attempting to require multiformats v12.x , which problematically is an ESM module and doesn't match our peer dependency in the contracts-sdk package.json.
