  [css-counter-styles] Enable new codepath for Korean counter styles

Reviewed by Myles C. Maxfield.

The spec defines all the Korean counter styles to have two trailing whitespaces for the negative suffix.
Trailing whitespaces in strings seem to be optimized too cleverly by the build system for UA sheets (this bug does not affect author counter styles).

Replace the second whitespace with \20 to make sure the build system doesn't strip the spaces.

This makes the following tests pass with the new codepath:
