emacs30: Mark broken with webkitgtk and switch to webkitgtk_4_1

We are removing `webkitgtk_4_0` let’s switch to 4.1 since emacs supports both.

Though the build system caps it to unmaintained versions:

    > checking for webkit2gtk-4.1 >= 2.12 webkit2gtk-4.1 < 2.41.92... no
    > checking for webkit2gtk-4.0 >= 2.12 webkit2gtk-4.0 < 2.41.92... no
    > configure: error: xwidgets requested but WebKitGTK+ or WebKit framework not found.

Let’s also mark webkitgtk support as broken.

(It is disabled by default since a755ead8efa1716cf72cdbe552835270281d65a6.)
