[SECURITY] Fedora 36 Update: mingw-expat-2.5.0-1.fc36

This is expat, the C library for parsing XML, written by James Clark. Expat is a stream oriented XML parser. This means that you register handlers with the parser prior to starting the parse. These handlers are called when the parser discovers the associated structures in the document being parse...
