Update scripts for new Fedora 39 based images for 4.2-beta3 and later

Follow-up to https://github.com/godotengine/build-containers/pull/128.

Also reverts #88 since these new images include JDK 17, and the closure
compiler issue was fixed upstream.

And removes the manual install of gettext which is now also part of the
images.

X11 libs should not be needed to generate the Mono glue anymore (they've been
unnecessary for a while already).
