Replaced old markdown Issue template with new GitHub forms templates (#3468)

This PR replaces the old markdown issue template with the new YAML based form templates for GitHub, this allows us to enforce required fields and also auto-tag with labels.

This doesn't remove the ability to open a blank issue, but it is obscured so it is not the primary thing people are likely to do.

This also added link entries in the issue creation page to link to the Discussions tab, Community Slack, and IRC channel.
