PR template should have examples of good release notes

[grantr]

Problem
Release note sections are useful for compiling release notes, but few PRs have them. @lberk suggested on slack that examples of useful release notes in the PR template might help new contributors know how to write them.

Persona:
Contributor

Exit Criteria
A new contributor is able to understand how to write a release note by looking at the PR template.

@grantr Since you have been taking care of releases for a while=. Could you quickly add an example based on one of the previous release notes?

This is on my list, but gets pushed down by higher priority things. I'll come back to it on 0.10 release day when release notes are top of mind.
