Add more css properties, shorthands

[lucyxiang]

Noticed that ACCEPTABLE_CSS_PROPERTIES is missing properties so adding some more (non exhaustive).

There’s a hodge podge of reasons why I choose these properties: I read through a bunch of “most common css properties / shorthands articles" and guesstimated what would be popular

@lucyxiang There are some failing tests because the existing shorthand CSS properties logic appears to have a bug that I'll need to dig into.

Can you break this up into two pull requests: one for the properties and keywords (which I think can be merged quickly), and another one for the additional shorthand properties (which I'll use to debug the failing tests)?

[flavorjones]

These properties and keywords look OK! There is one failing test, though, which looks like it's failing because the position property was previously disallowed but is now allowed. Are you able to update that test so it passes?

For Rails Conf 2024 hack day, maybe someone would be willing to put in a little bit more work to get this merged?

@flavorjones I'm continuing this work over in #283
