Develop -> Master Release PR

go/proxyd: Allow string RPC IDs

Metadata:

- Fixes ENG-1768

Renamed op-exporter and added CI

itests: remove old sync-tests

The sync tests would cover syncing of replicas and verifiers.
The replica syncing is now covered in the integration tests
which lets us remove the sync tests.

feat: translate SDK API spec to TS types

feat: add base SDK package

ops: pass through start block height to dtl

Without this explicitly configured, the `ops` package
would hang on my machine. It was incorrectly using a start height
greater than the size of the L1 chain

integration-tests: fee too low/too high

fix: deployer dockerfile

feat: hardhat fork mode

Adds forking config to the `ethereumoptimism/hardhat` docker image.
This can be configured with the following env vars:

- `FORK_URL` - http provider of the remote node to fetch data from
- `FORK_STARTING_BLOCK` - block to start forking from, if left
  undefined it will use the tip

Without `FORK_URL` set, it will not run in forking mode

Also adds the ability to configure the gas price with:

- `GAS_PRICE` - defaults to 0, which was the previous behavior
