* docs: add links to the issue tracker

Adding links to the issue tracker for existing issues and submission of
new issues makes it easier to do what is otherwise well described in the
issues doc.

There are direct links to the issue tracker in other introductory docs,
so I see no reason not to have them here, to facilitate access.
