Redirect stdin/stdou on linux container

[CarlosArmiliato]

Hi,

I'm using this project and i testd linux stdout redirection.
If i'm running on Linux OS, this project wil write html on file and read from there to generated PDF file.

I believe it is because stdin/stdou redirection wont be working in the past.
But i'm test now, with the last .Net5, and that work fine.

I only remove the else clausule, and alow the program perform the same code to Windows and Linux OS.
On the WkhtmlDriver class, the else reference if clausule on line 40:
if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows) || RuntimeInformation.IsOSPlatform(OSPlatform.OSX))

I think use stdin/stdou redirection are better then write and read from the disk.

Wath do you think about remove that "if" as i did?
Can i open pull request with this modification?
