AV Hosting API: Add example for uploading multiple code files via the code upload endpoint

[jrriehl]

The code can be uploaded as a single string (like the current example) or a JSON string with multiple file objects as follows:

import requests

data = {
    "code": '{[{"id": 0, "language": "python", "name": "agent.py", "value": <contents>}, {"id": 1, "language", "plaintext", "name": ".env", "value": <contents>},...]}'
}

pathParameters = {
    "agentAddress": "agent1q2dfhywtt8xazrdyzgap6gzdd7uhk4e0wmc3gjqt42esauaegcm8cuvclpj"
}

requests.put("https://agentverse.ai/v1/hosting/agents/{pathParameters.agentAddress}/code", json=data, headers={
    "Authorization": "bearer <your token here>"
}
