Simplify MASTER_SITES= GNOME in Makefile

[duchateau.olivier_gmail.com]

Summary

Since GNOME changes their numbering, in some Makefile MASTER_SITES= GNOME is more complex. This patch simplify for users.

Moreover, mark x11-toolkits/gnome-pty-helper BROKEN, because it is unfetchable.

^ it would likely make sense to not use GNOME_VER here, but something internal, like _gnome_ver.

Replace GNOME_VER variable by _gnome_ver

New attempt in order to simplify MASTER_SITES for GNOME ports when DISTVERSION >= 10.

Now gitlab.gnome.org is used as last resort, so it is located at the end of the list.

I found typos in 2 ports devel/tinysparql and x11/ptyxis. Regenerate makesum for these 2 ports because extension changed too.

Moreover I "bumped" PORTREVISION for devel/tinysparql because I have added a patch, otherwise it fails to find textproc/snowballstemmer.

These changes are needed for update of GNOME 47.
