Remove styling to allow switching answers-search-ui icon divs to spans (

#1169)

This PR removes styling that targets arbitrary `span`s in `Answers-resultsHeader`. This styling was being automatically applied to icons using the answers-search-ui partial (or other icons) when the `div`s were changed to `span`s for accessibility reasons, which caused visual regressions. This was only an issue on vertical full page map templates which include the search bar and nav tabs in `Answers-resultsHeader`, instead of just the results count and applied filters.

Based on the [PR](#900) that initially added this styling, this was needed to ensure results count elements had the correct ordering on both ltr and rtl experiences. I checked a vertical template and vertical full page map template for `en` and `ar` locales in the test site and the results count elements seem to still be flipped, as expected. The only other `span`s that I saw within `Answers-resultsHeader` seemed to be the nav More icon and applied filters, both of which seemed fine after removing this styling.

Since we no longer have a paid Percy subscription, our snapshots are not being generated. So I've included some screenshots of pages after the changes in this PR, pointing to v1.16.6 of answers-search-ui which contains the icon `div` to `span` change:
