fix docs/links for 1.14.0 release

This patch addresses the following issues in prep for the neutron-lib
1.14.0 release:
- Updates the tox linkcheck target to get it working.
- Removes the glob for modules/* in doc/source/reference/index.rst as
this causes local build errors when not finding anything with the glob.
- Fixes any issues found by running the linkcheck tox target.
