Please add hackage revision with `rio-prettyprint <0.1.4.0`

The latest version of stack (2.9.1) in hackage fails to build with cabal because the version of rio-prettyprint (recently released 0.1.4.0) chosen results in this error:

src/Stack/Build/Execute.hs:2174:57: error:
    Ambiguous occurrence ‘string’
    It could refer to
       either ‘Data.Attoparsec.Text.string’,
              imported from ‘Data.Attoparsec.Text’ at src/Stack/Build/Execute.hs:30:1-50
              (and originally defined in ‘attoparsec-0.14.4:Data.Attoparsec.Text.Internal’)
           or ‘RIO.PrettyPrint.string’,
              imported from ‘RIO.PrettyPrint’ at src/Stack/Build/Execute.hs:95:1-32

Adding a hackage revision with upper bound rio-prettyprint <0.1.4.0 should resolve this.

@hamishmack, thanks for reporting. Now fixed on Hackage.
