Chrome 144 :current support

[chrisdavidmills]

Summary

Chrome 144 supports the ::search-text pseudo-element, which allows custom styling to be applied to browser search results; see https://chromestatus.com/feature/5195073796177920.

We already have BCD for ::search-text, however, you can combine ::search-text with the :current pseudo-class to style the currently-highlighted search term on the page. This currently doesn't have any BCD, so I am using this PR to add :current BCD.

I'm assuming it makes sense to put Chrome 144 down for this as well, as previously, there was no context in which :current was supported. However, you might have other opinions on this.

I also thought about putting "partial_implementation": "true" for this, but then again, :current is fully supported in the context it is supported in. It just isn't supported in other contexts.

I'm wondering if we need to add an entry here in order for the collector to test this. @Elchi3 Do you know more?

PS: The collecto has a test for ::search-text, without it being mentioned explicitly in the repo.

It turns out there is a collector test for :current, but it fails in Chrome 144:

Either the feature isn't actually available in Chrome 144, or it is finched, or the collector test is insufficient.

In Chrome 144:

• CSS.supports("selector(:current())") returns false
• CSS.supports("selector(::search-text)") returns true

FYI, I've tested it on the latest Chrome release version (which is up to 144), and it works there. See https://pr42870.review.mdn.allizom.net/en-US/docs/Web/CSS/Reference/Selectors/::search-text#custom_styles_for_text_search_results (it should be live on MDN soon, as we just merged the associated content PR.)
