Apply prettier to css, html, js, md, ts, and yml (#1249)

* Apply prettier to css, js, html, md, ts, and yml

As a followup I will add prettier to the .pre-commit config.
This patch is 100% generated by prettier.
I used a forked version of prettier that understands the
py-script tag.
See https://github.com/hoodmane/pyscript-prettier-precommit
