Install instructions don't work (npm install fails to find holochain-conductor-api#dump-full-state)

[carlgieringer]

Following the instructions in the README for local development, the command npm install fails with this output:

[nix-shell:~/code/github/carlgieringer/holochain-gym.github.io]$ npm install
npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I'll try to do my best with it!

Looking in the debug.log, I see:

It looks like holochain-playground/core at HEAD depends on github:holochain/holochain-conductor-api#dump-full-state (package.json). Going to https://github.com/holochain/holochain-conductor-api redirects me to https://github.com/holochain/holochain-client-js. In that repo, I can't find a branch dump-full-state.

So I think we need to try updating the dependency in holochain-playground/core to /holochain/holochain-client-js. Hopefully it just works, but, if not, we might need to understand what was previously in the dump-full-state branch.

(While looking into this issue, I noticed a couple of other things:)

holochain-playground/core also depends on file:~/projects/holochain/open-dev/core-types, which won't work on my machine since I have a different folder structure.

This might be fixed by updating the dependency to holochain-open-dev/core-types.

(Also, why is the holochain-playground/core repo archived if the holochain-gym actively depends on it?)
