`css.types.ratio.number_value` has support, none is mentioned

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

css.types.ratio.number_value reports only implementation behind a flag in Firefox. The description is "Accepts a single <number>; as a value." This is in line with the spec definition of ratio, which accepts a single number, defaulting to 1.

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet), Firefox, Safari

What did you expect to see?

Some support, but I'm unsure of when it was added. Alternatively, if we're unable to determine when this was added, it may make most sense to just remove this key.

Did you test this? If so, how?

Start with the MDN ratio browser-compatibility page and the linked CSS Values 4 ratio specification, then compare the reported behavior using the supplied CodePen test. Determine whether browser support can be dated reliably or whether the number_value key should be removed; done means the compatibility data accurately reflects the finding.
