[ANN] NSubstitute 4.4.0 released

[David Tchepak]

Hi all,

We've released NSubstitute v4.4.0. This adds support for Castle Core v5, thanks to @Havunen (#690, #673), as well as fixing an issue checking for constructor args on null object, courtesy of @phongphanq, and @appel1 (#683, #685). Thanks also to @Mandroide for the code review. @Socolin has also added `.ThrowsAsync()` that will correctly mock exceptions on async methods (#609, #663).
