Build docker on PRs, and inline docker GHA config (#584)

* Docker: `poetry install` verbosely

* Now try building on ARM

* Don't use workflow repo's docker workflow

This config seemed to build arm wheels much more quickly and I've no
idea why!?!!

* Changelog

* Revert "Now try building on ARM"

This reverts commit c733ced.

* Remove bad copypasta
