Almost every use of "Not relevant" I see is the opposite -- it is relevant to have an example on try.gitea.io and often we can't do anything until the user provides one. Remove the not-relevant option so people have to decide yes/no if they are going to attempt to reproduce it which will hopefully encourage them to do so in simple cases.
For actual not-relevant issues No should be a fine answer as well as it would be clear to us when you can't reproduce an example there.
Hopefully this will encourage more examples when people file issues which would lead to quicker fixes.
I've noticed that a lot of issues cannot be reproduced on http://try.gogs.io,
which either hints about specific database type problems or
hints about bugs which are already solved in the newer version
(as http://try.gogs.io is usually a newer build).
This patch adds the suggestion to test the issue at http://try.gogs.io in
the Github "issue template". The user can answer: "Yes", "No", "Not relevant".
"Not relevant" is an option where testing on http://try.gogs.io makes no sense as
the bug is unrelated to the Web UI or is very specific in nature.
