build(deps): fix npm (grpc) build on NodeJS v20.4.0
Browse files Browse the repository at this point in the history 
WORK IN PROGRESS
--------------

1. Eliminates all uses of the old `grpc` dependency from the codebase.
1.1. Upgraded all outdated fabirc-network, fabric-client and fabric-ca-client
dependencies to the latest stable 2.2.x version which is 2.2.18 at the time.
1.2. Also outright swapped `grpc` declarations with `@grpc/grpc-js`.
The rest of the diff is due to the incompatibility of the two mentioned.

Fixes https://github.com/hyperledger/cacti/issues/2562
Fixes https://github.com/hyperledger/cacti/issues/1507
