As part of the move of the jfx repos to GitHub, we need to update all files in the repo that point to the HG repo on hg.openjdk.java.net.
The following third-party legal files have a pointer to the http://hg.openjdk.java.net/openjfx/jfx/rt repo:
modules/javafx.media/src/main/legal/glib.md: http://hg.openjdk.java.net/openjfx/jfx/rt
modules/javafx.media/src/main/legal/gstreamer.md: http://hg.openjdk.java.net/openjfx/jfx/rt
modules/javafx.web/src/main/legal/webkit.md: http://hg.openjdk.java.net/openjfx/jfx/rt
This needs to be updated to: https://github.com/openjdk/jfx
