* chore: configure proper link to discourse.gohugo.io
This adds a configuration file to the issue templates for this repo. In this config file, an issue template is added that will look like the existing issue templates, but on click will lead directly to the discourse forum instead of hoping that people read what it says there. The support.md can be deleted.
* chore: remove obsolete support.md configuration
* chore: remove obsolete autoclosing workflow
