Wrong type annotations in Collection filters

[lyokha]

Docs annotate some Collection filters wrongly.

-- [@reverse :: Collection -> Scientific@]
-- /See/: Text.'Data.Text.reverse', Vector.'Data.Vector.reverse'
--
-- [@head :: Collection -> Scientific@]
-- /See/: Text.'Data.Text.head', Vector.'Data.Vector.head'
--
-- [@last :: Collection -> Scientific@]
-- /See/: Text.'Data.Text.last', Vector.'Data.Vector.last'
--
-- [@tail :: Collection -> Scientific@]
-- /See/: Text.'Data.Text.tail', Vector.'Data.Vector.tail'
--
-- [@init@ @:: Collection -> Scientific@]
-- /See/: Text.'Data.Text.init', Vector.'Data.Vector.init'
--
-- [@'Data.HashMap.Strict.keys' :: Collection -> Scientific@]
--
-- [@'Data.HashMap.Strict.elems' :: Collection -> Scientific@]

They all return Scientific which is apparently wrong.
