Stan interface notebook is broken

[MichaelClerx]

Couple of warnings, then an error when building

Building: 32.0s, done.Messages from stanc:
Warning in \'/tmp/httpstan_ioc8i20p/model_vdpin3fp.stan\', line 4, column 2: Declaration
    of arrays by placing brackets after a variable name is deprecated and
    will be removed in Stan 2.32.0. Instead use the array keyword before the
    type. This can be changed automatically using the auto-format flag to
    stanc
Warning in \'/tmp/httpstan_ioc8i20p/model_vdpin3fp.stan\', line 11, column 17: A
    normal distribution is given parameter sigma as a scale parameter
    (argument 2), but sigma was not constrained to be strictly positive.
Warning: The parameter sigma has no priors.
Warning: The parameter mu has no priors.
