Add documentation for docstring template generation with multi-format support

[Copilot]

The python.analysis.supportDocstringTemplate setting exists but lacks documentation. Users don't know it provides automatic docstring generation with Google, NumPy, and Sphinx format support.

Changes

New Documentation (docs/settings/python_analysis_supportDocstringTemplate.md)

• Feature overview and configuration steps
• Examples for Google, NumPy, and Sphinx docstring formats
• Usage patterns: automatic """ trigger and code action invocation
• FAQ covering style detection, customization, and integration

Enhanced README.md

• Expanded setting description with template generation example
• Added link to detailed documentation
• Clarified trigger mechanisms

Updated FAQ.md

• Added "How do I enable automatic docstring template generation?" entry
• Linked to comprehensive documentation

Example

def calculate_total(price, quantity, discount=0):
    """  # Type """ triggers auto-generation
    # Produces:
    # """[Summary]
    #
    # Args:
    #     price: [description]
    #     quantity: [description]
    #     discount: [description] (default: 0)
    #
    # Returns:
    #     [description]
    # """

Feature enabled by default in full language server mode; manual enable required for default mode.

I've completed the documentation for the python.analysis.supportDocstringTemplate setting with Google, NumPy, and Sphinx style examples. The PR includes:

• New comprehensive documentation page (docs/settings/python_analysis_supportDocstringTemplate.md)
• Enhanced README.md with detailed examples
• FAQ entry for discoverability

Could you clarify what you'd like me to continue with? Are there specific aspects of the documentation that need expansion or revision?
