    ApplicativeDo: handle BodyStmt (#12143)
    
    Summary:
    It's simple to treat BodyStmt just like a BindStmt with a wildcard
    pattern, which is enough to fix #12143 without going all the way to
    using `<*` and `*>` (#10892).
    
    Test Plan:
    * new test cases in `ado004.hs`
    * validate
