chore(deps): replace plebbit/plebbit-react-hooks with bitsocialhq/pkc-react-hooks

bitsocialhq/pkc-react-hooks is a fork of plebbit-react-hooks that we're maintaining temporarily as an attempt to modernize the original repository using AI tools, possibly merging changes back into plebbit-react-hooks, which should also be rebranded to pkc-react-hooks eventually, under the org pkcprotocol.
