check_ssh: Handle non-alpha software versions

This patch fixes a bug where we would reject version control strings
that do not contain letters, because the assumption is made that they
always do. This is not required by the RFC however, and there exist
implementations that do not contain letters.

I've also added a few references to the RFC to make the process of
parsing the control string more apparent.

This fixes op5#8716 (https://bugs.op5.com/view.php?id=8716)
