Add Presentation Request issue template

[kilasuit]

Hi @kilasuit, thanks for opening this — could you add a bit more detail before we move on it?

Specifically:

• Use case: Is this template intended for people to request a maintainer/community member to deliver the DscWorkshop as a presentation (at a user group, conference, internal event, etc.), or for requesting new presentation/slide content to be added to the repo, or something else?
• Audience: Who would file these issues — end users, event organizers, contributors?
• Fields: What information should the template collect (event name, date, audience size, format, target topics, contact info, …)?
• Outcome: What should happen after the issue is filed — assignment to a maintainer, triage label, redirect to Discussions?

Once the intent is clearer we can decide whether an issue template is the right vehicle (vs., say, a Discussions category or a section in the README), and then design the fields accordingly.
