Add poetry.toml to Python.gitignore (optional Poetry config file)

[vicman7]

Reasons for making this change

This change adds .poetry.toml to the Python .gitignore file.

.poetry.toml is a configuration file used by Poetry, a widely adopted dependency management and packaging tool in the Python ecosystem. While .poetry.toml is typically used for local configuration (e.g. virtualenv location or group settings), it often contains machine-specific paths and preferences that should not be committed to version control. This makes it a good candidate for inclusion in .gitignore.

The change follows the convention already applied in the template for similar tools like Pipenv and PDM, where their lock/config files are commented out or ignored based on user/project preference.

Thanks for this! I agree this is probably an optional change for most repositories, and think having it commented here makes sense 👍
