[TASK] Outstanding Issues in Multi-Chain Feature for SDK

[satyajeetkolhapure]

On the branch, the feature to call multi chain is implemented. Although there are below remaining open issues need to be fixed.

1. The .graphclientrc.yml file points to resolvers.ts which works examples in sdk but in explorer packaging it needs to change to resolvers.js. The js extension doesn't work with examples. Find a way which works for both browser and console examples

additionalResolvers:
  - ./src/resolvers.ts

2. The .graphclient code generated using graphclient build command has syntax error

Uncaught SyntaxError: Unexpected string

The similar issue seems to be reported by others as well e.g this issue

Fix this issue trying different versions which are compatible with vite version

3. An other issue appeared while fixing the first 2 ones:
   While the SDK is now compatible with a frontend environment, its own dependencies uses process.env notations, which you be "polyfilled" to make them useable in such an environment.
