- Adds issue type to each template
- Differentiates user-submitted "Change Request" from internal "Planned
Feature". This allows us to separate user-submitted ideas from work
we've planned through the new feature workflow, and automatically set
the github project.
- Adds template for docs change
- Makes additional context section optional, I noticed many issues put
"n/a" or similar in this section anyway.
- Disables blank issue adds generic "Task" issue template
