Add PdfSharp font resolver for .NET 8 compatibility

Browse Source 
Added a `PdfSharpFontResolver` class to enable font resolution
for PdfSharp in .NET 8, addressing the lack of system font
access. The resolver reads fonts from the Windows Fonts folder
and supports the Arial font family. Registered the resolver
globally in `Program.cs` using `GlobalFontSettings.FontResolver`.

Updated `Program.cs` with comments explaining the necessity of
the resolver for .NET 8. The resolver includes methods to map
font family names to specific font files and load font data.
Throws a `FileNotFoundException` if required fonts are missing.

Made minor formatting changes in `Program.cs` without altering
the `SwaggerDoc` description functionality.
