GitHub issue template for general questions

[Dr. Matthias St. Pierre]

Hi,

I noticed that a lot of issues on GitHub containing general questions get tagged as a [bug],
because the template list only gives the choice between two options, a *Bug Report* and
a *Feature request*. (There is a third choice in tiny letters, which usually gets overlooked.)
A recent example is https://github.com/openssl/openssl/issues/9743.

For that reason, I would like to suggest adding a third template, which creates issues tagged
as  [question]:

  *Bug report*
    Report a defect in the software
  *Feature request*
    Propose a feature you would like to see added in the software
  *Question*
    Ask a general question about the software

I am aware that this third category was probably omitted on purpose, because we would rather
see those questions asked on the openssl-users mailing list, but the practice shows that user
interaction on the mailing lists is fading and more and more user questions are being asked on
GitHub. What do you think about the suggestion?
