Tweak bug report template

These checkboxes keep getting checked despite the submitter using an
insecure context or not having tested upstream.  I think two things are
at play here:

1. Folks might be interpreting "cannot reproduce" as "did not
   reproduce" or "did not have time to reproduce".
2. The checkboxes are required to submit the issue so folks might be
   marking them just so they can get their issue submitted; maybe they
   are not even reading the checkboxes and are just seeing the error
   that they need to be marked and blindly marking them because while
   in some cases folks will add "I had to check this but it is not
   true", usually they say nothing.

In any case, hopefully these changes make the checkboxes more accurate,
and then if they are unchecked we can ask them to go reproduce in VS
Code or use a secure context or whatever the case may be.
