[BUG] Confusing title in docs/platform_specific_build_instructions.md

Abre docs/platform_specific_build_instructions.md y lee la sección titulada "Building with Visual Studio 2015, 2017 or 2022" junto con el contexto de build de Windows indicado. Actualiza la documentación para que el encabezado y el texto dejen claro que las instrucciones también se aplican a mingw-w64-ucrt-x86_64 y, después, verifica que la sección renderizada ya no resulte engañosa.

Describe the bug
In the file https://github.com/google/benchmark/blob/main/docs/platform_specific_build_instructions.md, there is a section titled "Building with Visual Studio 2015, 2017 or 2022". The instructions are not specific to Visual Studio, and the heading is therefore misleading.

I am working on Windows 11 25H2 and using the mingw-w64-ucrt-x86_64-toolchain for compilation and linking: gcc 16.1.0, ld 2.46; and ninja 1.13.2 for the build.

I built the library using the tools mentioned above and then tried to run the code from the "Usage" section of the README, linking against the static library build/src/libbenchmark.a.

The code snippet:

#include <benchmark/benchmark.h>

static void BM_StringCreation(benchmark::State& state) {
  for (auto _ : state)
    std::string empty_string;
}
// Register the function as a benchmark
BENCHMARK(BM_StringCreation);

// Define another benchmark
static void BM_StringCopy(benchmark::State& state) {
  std::string x = "hello";
  for (auto _ : state)
    std::string copy(x);
}
BENCHMARK(BM_StringCopy);

BENCHMARK_MAIN();

Compilation:

I was able to fix the error using the solution described in this Stack Overflow post: https://stackoverflow.com/questions/78600881/undefined-references-when-linking-google-benchmark-with-g-on-windows-msys2-u?newreg=d8053eb47e674ea6a805c335e7e46134

I spent a relatively large amount of time troubleshooting this issue because the section heading in https://github.com/google/benchmark/blob/main/docs/platform_specific_build_instructions.md#building-with-visual-studio-2015-2017-or-2022 is misleading and suggests that the instructions are only relevant to Visual Studio.

I think it would be worth mentioning that these instructions are also applicable to mingw-w64-ucrt-x86_64.
