ci: question.yml - Clarify that the issue tracker is not for personal support (#3498)

* ci: Revise `question.yml` to better clarify the issue tracker is not for support queries

Users have been making low effort reports (_bypassing the dedicated form_) through this alternative that is intended for addressing other concerns related to the project - not troubleshooting user problems.

When a user does not want to put the effort in of a full bug report (_and following our debug docs tips that it refers them to_), they should be using the Github Discussions page which provides the same free-form input, but should not require attention of project devs (contributors / maintainers).

The markdown rendered field above the "Description" input field didn't seem too relevant for this template. I've opted for a markdown comment (so it won't render if kept) into the input field with hopes that'll be more visible to the readers attention.

* chore: Fix typo
