Fixing the automatic generation of Tex info node names

[Philip Kaludercic]

For some reason ox-texinfo removes periods from node names.  It seems
this is not necessary as info can render these files without any issues,
and in certain cases not intended (e.g. I had a node named "Emacs 28.1"
and it was abbreviated to "Emacs 281").

This patch should resolve the issue:
