Upgrade to XPDF 4.04

I've sucessfully compiled the v4.02 version
But when i try the same with the sources of v4.04 in "xpdf-4.04" on Windows 10 (Using Visual Studio 2022) i get an error when trying to compile
I've renamed the 4.02 version and folder names to 4.04 in the /CMakeLists.txt and "/libxpdf/.github/workflows/build.yml"
(also tried to place the 4.04 sources in the 4.02 folder)
```

src\pyxpdf\xpdf.cpp(836): fatal error C1083: Cannot open include file: 'Form.h': No such file or directory
```

Any help appreciated !

Update: managed to compile 4.04 sources by changing cmake-config.txt and CMakeLists.txt files ( as compared to 4.02 )
but i don't know if this is a stable solution .....

Compare CMakeLists.txt and cmake-config.txt between the working 4.02 sources and the 4.04 sources, including the referenced libxpdf/.github/workflows/build.yml. Reproduce the Visual Studio 2022 build and inspect the xpdftest link failure involving src/pyxpdf/xpdf.cpp and the missing Form.h. Done means the 4.04 sources build successfully with a stable, documented configuration.
