feat: python/create-onchain-agent - improved cli network selection & template selection

[CarsonRoscoe]

Description

The main focus of this PR is to print it up to parity with #485.

In addition, this:

1. Bumps the cli to use the Python AgentKit version 0.1.4 (needed for improved custom chainId/rpcUrl handling via feat(py): configurable eth account wallet provider rpc_url #474 )
2. Improves local development of the cli by passing in a --template flag, which allows you to point to a local template instead of downloading the template from git.

Tests

Manual testing down the branches, both with and without the template flag

To manually test, from python/create-onchain-agent run:

poetry install
poetry build
poetry run python3.10 ./create_onchain_agent/cli.py --template ./templates/chatbot
