Remove 'or any later version' license choice

Recent drama about FSF leadership continuity makes this less clearly

My intention is to add future license versions to this list after
verifying that they are of similar character and spirit to past
versions.

Previous versions of this software, of course, retain the 'or any later
version' license choice option.
