Use a dl rather than a table for attr values

[wbamberg]

This removes the inline styles from https://developer.mozilla.org/en-US/docs/Web/CSS/attr(). The page used a table for values of the <type-or-unit> value, and then used white-space: nowrap; to stop the type names from wrapping.

I've chosen to replace the table with a nested dl:

• this is a more conventional way to do this in our docs
• it will work better in Markdown than a table
• it gives the main text for each item more horizontal space rather than squeezing it into a cell

I dropped the "Associated type" bit because it seemed obvious from the description.
