[CI][Docs] doxygen fails on Complete Documentation on cpp/src/arrow/flight/sql/odbc/README.md

[raulcd]

Describe the bug, including details regarding any error messages, version, and platform.

The AMD64 Debian 12 Complete Documentation fails on main with:

/arrow/cpp/src/arrow/flight/sql/odbc/README.md:29: error: Found unknown command '\to' (warning treated as error, aborting now)

Doxygen seems to be interpreting this as a command:
https://github.com/apache/arrow/blame/5b1af01098f9281e7c04c5017a7f5232a683f646/cpp/src/arrow/flight/sql/odbc/README.md#L29

This was introduced when the ODBC Windows installer was merged:

• [C++][FlightSQL][ODBC] Windows Installer #47787

Component(s)

Continuous Integration, Documentation
