Improving local dx

[ajaralampidis]

Description

• Updated readme showing: pre-requisites, dependency installation, step by step to run local chain + local subgraph
• Updated .gitignore files to avoid tracking auto-generated files:
  • subgraph.yaml is autogenerated
  • subgraph abis are copied from hardhat
• Fixed some issues along the way because local subgraph was not working correctly
  • networks.json was hardcoded and locally we deploy contracts every time we spin up a new hardhat chain
  • prepare-local-manifest.ts now seeks the address from hardhat/deployments directory (dynamically)
  • I had to add a chain:local script adding the --hostname 0.0.0.0 flag. This is required to allow The Graph node to connect to the local RPC created by hardhat.

No screenshot since there are no visible changes, this PR is mostly about development experience

I don't have access to Vercel to see what is failing in the build. I tried guessing but I couldn't. Locally I can run everything
