Issue templates

[andreped]

This PR fixes issue #223.

CIs are not required for this PR, so I added [no ci] for all commits.

Any comments regarding adding these issue templates, @NickCrews?

Feel free to suggest corrections/improvements :]

At least I think having this would increase the user friendliness for new users/contributors.

those look good! Can always edit them if we find that people are giving bad reports due to the framework.

Potentially could add a vanna.show_versions() command, similar to pd.show_versions(), so that people are acually likely to fill it out, and we get all the env info we need, including other PyPI packages. But that could come later.

Thats a cool idea. I guess it would make sense to tailor these templates based on what people might ask. This I am not really qualified for, as I have yet to use this framework nor know the user base.

However, by having these templates, maintainers should quickly note what people tend to add in addition to these templates (or if they remove sections in general), which then should give them some hints on how they could be refined.
