Fix #60

We dropped support for node 6 and 8 with version 3, but didn't update
the package.json file.  This corrects that oversight.

In a previous refactor we add a length count to strict a little bit more
the regex that identifies gists, unfortunately it drops support to
legacy gists that had less than 32 characters hashes,
ref: d5cf830

This changeset fixes it by reducing that count to 7 (which is the
smallest hash length found in tests from our package ecosystem) that
seems to have been in use until at least late-2012.
