Vulnerable dependency System.Drawing.Common

This just to let you know that FlaUI v4 currently gets flagged by tools such as osv-scanner due to its dependency on a vulnerable version of System.Drawing.Common. The problem is described here: https://osv.dev/vulnerability/GHSA-rxg9-xrhp-64gj

I'd guess this is a simple matter of bumping the dependency past the vulnerable range for the next release.
