Fix unresolved xref placeholders in message_mapper.py DocFx output

[Copilot]

Short RST :class: roles (e.g. :class:InputMessages``) cause DocFx to emit unresolvable <xref:InputMessages> placeholders in generated API docs instead of rendered links.

Changes

• agentframework/message_mapper.py — Replace all four :class:`` occurrences (module docstring, map_input_messages, map_output_messages, _map_role`) with plain double-backtick code formatting
• openai/message_mapper.py — Same fix for map_input_messages and map_output_messages return-value docs

Before / After

# Before — triggers unresolvable <xref:InputMessages> in DocFx
"""
This mapper converts them to :class:`InputMessages` / :class:`OutputMessages`.
...
Returns:
    Serialized :class:`InputMessages` JSON string, or ``None`` if ...
"""

# After — plain code formatting, consistent with langchain/message_mapper.py
"""
This mapper converts them to ``InputMessages`` / ``OutputMessages``.
...
Returns:
    Serialized ``InputMessages`` JSON string, or ``None`` if ...
"""

Pull request overview

Fixes DocFx API doc generation by avoiding short RST :class: roles that DocFx renders as unresolved <xref:...> placeholders in generated documentation.

Changes:

• Replace :class: references with double-backtick inline code in Agent Framework message_mapper.py docstrings (module + function docs + helper doc).
• Apply the same docstring formatting fix to OpenAI message_mapper.py return-value docs.
