set astroAllowShorthand to default off (#143)

* set `astroAllowShorthand` to default off

Shorthand removes attribute keys and breaks Typescript which is used by Astro. It's also uncommon and should be disabled by default, and only opt-in for those that specifically want it.

* Create selfish-cherries-grab.md

* fix tests for shorthand formatting

- shorthand off by default
- comment (and should remove) can format to shorthand because this is covered in the options test

* remove obsolete shorthand tests, update changeset
