Switch from webkit2gtk 4.0 to 4.1
@ebourg We are trying to remove the 4.0 version of webkit2gtk from Debian. 4.1 is the same as 4.0 except that it uses libsoup3 instead of libsoup2.4.
https://release.debian.org/transitions/html/webkit2gtk-4.0.html
It looks like biglybt is the only thing that uses libswt-webkit-gtk-4-jni
in Debian.
[webkitgtk.h](bundles/org.eclipse.swt/Eclipse\ SWT\ WebKit/gtk/library/webkitgtk.h) already handles libwebkit2gtk-4.1-0
