[GHC-02256] "Ambiguous record update" is not documented.

[rickowens]

I am opening an issue that this error is undocumented as requested by the errors.haskell.org homepage.

The full error looks something like this:

redacted-file.hs:395:7: error: [GHC-02256] [-Wambiguous-fields, Werror=ambiguous-fields]
    Ambiguous record update with parent type constructor ‘RedactedConstructor’.
    This type-directed disambiguation mechanism will not be supported by -XDuplicateRecordFields in future releases of GHC.
    Consider disambiguating using module qualification instead.

Thanks for the report. I'll try to get to it soon :)
