Rename options param of #time_ago_in_words to match API change

Rename `include_seconds_or_options` to `options` to match 6b9356a (which removed the deprecation introduced by #6077).  This has no functional impact because the parameter is passed directly through, but makes it clearer that the parameter no longer supports a boolean as input.
