[css-gaps-1] Naming bi-directional gap decoration shorthand

[kbabbitt]

Gaps 1 defines the gap-rule property as a shorthand which sets widths, styles, and colors in both the row and column directions.

In the TAG review thread for CSS Gap Decorations, @LeaVerou asked:

Why gap-rule and not just rule which would be consistent with the row-gap/column-gap/gap shorthand?

To which I responded:

I was a little concerned about overloading a general term like "rule" in case we at some point discover some other place we want to paint rules, and to avoid confusion between a CSS rule and the CSS rule property.

I wanted to open a discussion to get more opinions from the WG about this. What do folks think?
