add threads:off to examples config file

[ringabout]

Hello the maintainers of the nim-plotly. Nim v2 will make threads:on derfault. It seems that nim-plotly behaves differently with and without threads:on. So I add a config file to make sure it continues to compile.

Ref https://github.com/nim-lang/Nim/pull/19368

There is indeed a difference with/without threads but it's still supposed to work in both case.

Does this cause CI issue ?

Yeah, here is the error message:

I think I'd prefer to fix the underlying issue that the code is broken in one case instead of forcing --threads:off there. I'll try to fix it now. If for some reason I don't manage for now, I'll merge this instead.

Thank you！

This should be unnecessary now. :ok_hand: Ping me if I'm wrong.

It works, thank you again!
