[csswg-drafts] Pull Request: [css-writing-modes] Fix source to match rendering in example

== [css-writing-modes] Fix source to match rendering in example ==
The rendering in the example shows the Gurmukhi character ji (ਜੀ)
but the source code had "ji" in latin alphabet, which would not result
in the expected rendering. This commit makes the source match the
rendering.

See https://en.wikipedia.org/wiki/Gurmukhi
