Subject: [PATCH] yaml-cpp: fix build with gcc15

- add patch from merged upstream PR that adds `include <ctdint>`:
https://www.github.com/jbeder/yaml-cpp/pull/1310
https://github.com/jbeder/yaml-cpp/commit/7b469b4220f96fb3d036cf68cd7bd30bd39e61d2

Fixes build failure with gcc15:
```
/build/source/src/emitterutils.cpp:221:11: error: 'uint16_t' was not declared in this scope
  221 | std::pair<uint16_t, uint16_t> EncodeUTF16SurrogatePair(int codePoint) {
      |           ^~~~~~~~
/build/source/src/emitterutils.cpp:13:1: note: 'uint16_t' is defined in header '<cstdint>'; this is probably fixable by adding '#include <cstdint>'
   12 | #include "yaml-cpp/null.h"
  +++ |+#include <cstdint>
   13 | #include "yaml-cpp/ostream_wrapper.h"
```
