Deploy a Safe singleton factory to a new network.

This tool wraps the NPM scripts 'estimate-compile' and 'submit' and:
1. Parses the RPC URL from a GitHub issue
2. Fetches the deployer mnemonic from 1Password
3. Automatically creates the GitHub PR for adding the deployment

USAGE
    github-deploy.sh [ISSUE]

ARGUMENTS
    ISSUE       The GitHub issue number of the 'new-chain' issue to deploy the
                Safe singleton factory for. If no issue is specified, all
                GitHub issues that are ready to deploy will be listed.

EXAMPLES
    List all issues that can be deployed:
        github-deploy.sh

    Deploy Safe singleton factory for GitHub issue #42:
        github-deploy.sh 42
