Replace os.environ with dotenv for better environment variable manage…

…ment Fixes #68 Update code samples to use `python-dotenv` for environment variable management. * **02-explore-agentic-frameworks/code_samples/02-autogen.ipynb** - Import `load_dotenv` from `dotenv`. - Add `load_dotenv()` after the import statements. - Replace `os.environ` with `os.getenv` for accessing environment variables. * **02-explore-agentic-frameworks/code_samples/02-semantic-kernel.ipynb** - Import `load_dotenv` from `dotenv`. - Add `load_dotenv()` after the import statements. - Replace `os.environ` with `os.getenv` for accessing environment variables. * **04-tool-use/code_samples/04-semantic-kernel-tool.ipynb** - Import `load_dotenv` from `dotenv`. - Add `load_dotenv()` after the import statements. - Replace `os.environ` with `os.getenv` for accessing environment variables. * **04-tool-use/code_samples/04-sematic-kernel-python-aiagent-bookinghotel.ipynb** - Import `load_dotenv` from `dotenv`. - Add `load_dotenv()` after the import statements. - Replace `os.environ` with `os.getenv` for accessing environment variables. * **05-agentic-rag/code_samples/05-autogen-chromadb.ipynb** - Import `load_dotenv` from `dotenv`. - Add `load_dotenv()` after the import statements. - Replace `os.environ` with `os.getenv` for accessing environment variables. * **07-planning-design/code_samples/07-autogen.ipynb** - Import `load_dotenv` from `dotenv`. - Add `load_dotenv()` after the import statements. - Replace `os.environ` with `os.getenv` for accessing environment variables. * **requirements.txt** - Add `python-dotenv` to the list of dependencies. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/microsoft/ai-agents-for-beginners/issues/68?shareId=XXXX-XXXX-XXXX-XXXX).
