insights: Add patternType UX indicators to the search query bar, to match main search bar

Created by: Joelkw

Our new syntax highlighting in 3.35 led a user to believe they didn't need to indicate patternType:regexp in their query, though they did. On capture group insights, we have the regexp indicator on the search creation bar (but uneditable).

Could we add the normal search indicators to our search creation bar to continue to bring it up to par with our search functionality?
