Bug report templates use Minitest

[Sean]

@deivid-rodriguez the bug report templates use Minittest which the Ransack tests are written in RSpec.

I hadn't previously noticed the Bug report templates but I think they are a great idea, especially if failing tests in the bug report templates could be added to the Ransack specs as part of a correcting PR.

Just wondering why they are in Minitest, and is there any reason that they should be converted to RSpec?
