Update Folly stack to the latest 2023.10.16.00 tag proxygen: Security fix for CVE-2023-44487

Summary

Proxygen comprises the core C++ HTTP abstractions used at Facebook.

Internally, it is used as the basis for building many HTTP servers, proxies,

and clients. This release focuses on the common HTTP abstractions and our

simple HTTPServer framework. Future releases will provide simple client APIs

as well. The framework supports HTTP/1.1, SPDY/3, SPDY/3.1, HTTP/2, and

HTTP/3. The goal is to provide a simple, performant, and modern C++ HTTP

library.
