Python: Add requirements.txt and .env.example to the a2a/ sample for pip-based setup (#5510)

* Add requirements.txt and .env.example to a2a sample

Beginners following the a2a/ sample had no pip-based install path:
the directory lacked requirements.txt and .env.example, unlike every
other 04-hosting/ sample.

- Add requirements.txt with editable local package paths matching the
  pattern used in azure_functions/ and similar hosting samples
- Add .env.example documenting FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL,
  and A2A_AGENT_HOST
- Update README Quick Start to cover both pip (.venv) and uv workflows

* Python: Add `requirements.txt` and `.env.example` to the `a2a/` sample for pip-based setup

Fixes #5395

* fix(a2a-sample): address PR review feedback for issue #5395

- Remove 'from repo root' wording from Option B uv heading in README
  to avoid contradicting the 'run from this directory' instruction
- Fix A2A_AGENT_HOST default in .env.example from 5001 to 5000 to match
  function-tools flow; add clarifying comments about port usage
- Add note for pip users explaining they can replace 'uv run python'
  with 'python' once the virtual environment is activated
