.github/ISSUE_TEMPLATE: ask for last known working version

Currently it asks which version introduced the problem, but
users are unlikely to know if they don't update and test every
single version released, and this field is rarely filled in
practice by non-developers.

On the other hand, it's much easier to recall the last working
version that they have used before.

So ask for the last known working version, which is useful
information for developers to narrow down bisecting range.
Also ask when did the issue start in general since the issue
can be caused by system or driver updates.
