"Invalid C++ declaration" with C++ lambda expression

Describe the bug

When building the Apache Arrow docs, we get the following warning:

/home/antoine/arrow/dev/docs/source/cpp/api/dataset.rst:62: WARNING: Parsing of expression failed. Using fallback parser. Error was:
Error in postfix expression, expected primary expression or type.
If primary expression:
  Invalid C++ declaration: Expected identifier in nested name. [error at 59]
    std::function< Status(FileWriter *)> writer_pre_finish   = [](FileWriter*) {returnStatus::OK();}
    -----------------------------------------------------------^
If type:
  Invalid C++ declaration: Expected identifier in nested name. [error at 59]
    std::function< Status(FileWriter *)> writer_pre_finish   = [](FileWriter*) {returnStatus::OK();}
    -----------------------------------------------------------^

How to Reproduce

The build procedure is a bit too complex to reproduce here. But I don't think that matters since the context is clear from the warning message above.

Expected behavior

Ideally there's a way to silence the warning. I understand that parsing C++ is hard, so I'm not necessarily expecting Sphinx to get it right in all cases :-) But the warning is distracting.

Additional context

No response

Start with docs/source/cpp/api/dataset.rst and the reported Sphinx C++ declaration parsing warning; reproduce it through the Apache Arrow documentation build if possible. Trace the relevant parser or configuration entry point using the stated Sphinx 4.3.2, Breathe 4.31.0, and Doxygen 1.9.2 versions, with completion marked by handling the lambda without a distracting warning or identifying a way to silence it.
