Simple implementation of "did you mean" for language suggestions. The suggestions will show up if the query consists of 2 or 3 terms, no filters and the first term is a language name (happy to adapt those rules to unlimited terms).
I chose the version with the darker background color because
it looked a bit "detached" without a background
with the white background it looked too similar to search results
I made the whole line into a link and omitted the "Run search" link. I felt there were too many variations of font styles with the query, the "Run search" link and the description.
Note: I also made some changes to SearchResultsInfoBar.tsx so that the buttons would line up properly if there are no search results (see last screenshot).
Test plan
Verified that clicking the link applies the new search
Suggestions are not shown if first term is not a language, or there are less than 2 or more than 3 terms, or the query contains a filter.
Colors look correct in dark mode
Container correctly aligns in smaller windows
