test(docs): ensure defaults are consistent

[ST-DDT]

Created after seeing #2175.
Unfortunately there is currently no way to automatically detect issues where the jsdocs on the signature level differ from those on the options object because typedoc erases the signature ones if the option's one is present. But I found a way to at least check that the options one is present. And that the not-option ones match the js impl default one.

(it also can only check the last api signature)

Should we use Defaults to `{}`. everywhere or nowhere? I implemented this for ~10/50 locations.

Team decision

We will omit/remove the empty options default for now in the jsdocs.
We will ensure all options parameters have a JS default value such as {} to ensure proper api docs defaults. (e.g. the color module doesn't have them yet) (separate PR: #2432)
