[css-regions] Editorial note: flow-from: inherit

Hello,
Currently the spec explicitly lists `inherit` as a possible value for the `flow-from` property[1]. However, this does not make sense, since it will either become a `none` or introduce a cycle, thus leading to it being ignored.

Since every CSS property actually accepts the `inherit` value, I suggest removing it from the list of explicitly supported values for `flow-from` and adding a separate note about it. Also, I suggest adding a “disclaimer” paragraph[2] about `inherit` at the beginning of the Regions spec, too.

Thanks,
m.
