Add making Issues for known users to the release checklist. c.f. pyhf/user-projects#6

@alexander-held has properly noted that depending on use feedback this is perhaps too invasive. So hold off on adding this to the release checklist.

@lukasheinrich @kratsg Can you please carefully read through these and give feedback?

https://pyhf--1705.org.readthedocs.build/en/1705/release-notes.html#release-v0-7-0

The amount of information in here is pretty dense, given that this is a whole year of development. I'm going for trying to promote the things that a user would care about in "Important Notes" and then expanding on them and adding technical notes and additions that a developer would care about in the other sections.

Revisions welcome!

[kratsg]

this phrasing is confusing as it implies that this is a change to pyhf.pdf.Model (it's not, but a change to schema validation to allow tensor types - also needed for diffability)

[kratsg]

need to mention #1818 and #1753

[matthewfeickert]

@lukasheinrich approved over Skype, so going to merge.
