Add deployment guide and update jamftf runner/config

[filip-patafta]

Summary

• Add a deployment-focused README (README.deploy.md) documenting the correct setup and execution flow.
• Update jamftf_runner.py to work with the current jamfpy client and generate Terraform imports.hcl plus optional JSONL dumps.
• Adjust jamftf.config.json to reflect a realistic example of enabled Jamf resource types.

Details

• Clarifies Python 3.10+ requirement due to jamfpy type hints.
• Documents environment variables (JAMF_URL, JAMF_CLIENT_ID, JAMF_CLIENT_SECRET) and the jamftf_runner.py CLI flags.
• Ensures the example config uses the correct provider resource tags.

Testing

• Created a fresh venv with Python 3.10+.
• Installed jamfpy from GitHub and jamftf via pip install -e ..
• Ran python jamftf_runner.py --config jamftf.config.json --out imports.hcl --dump item_dump.jsonl against a Jamf tenant and verified that imports.hcl and the dump file were generated.
