Describe what a changelog is in the documentation

[lwasser]

In this Pr it was noted that while changelog is shown in the example Python package structure (see here) it is not mentioned in the documentation docs section. So we need to add some content on changelog best practices / link to existing resources. many thanks to @ucodery for identifying this gap. ✨

This would be a new page i think in the packaging guide and we could link to it from the peer review guide.

https://keepachangelog.com might be helpful, either to link out to or to crib from

oh wow - that's a great resources, @dstansby !! many thanks for this note. also pinging @ucodery . we will go back and edit this section to add info on changelogs. that was quite the oversight on my part!! All - feel free to open a PR if you have time - otherwise i will get to this but it might take a bit of time for me to get there!!
