[warn] Ignored unknown option --stdin

[arichiardi]

Hi there, started to use this package and receiving that warning when try to call (prettier-js).

$ prettier -v
2.3.2

and

$ prettier --help | grep stdin
  --stdin-filepath <path>  Path to the file to pretend that stdin comes from.

Sorry not really upto snuff on the JavaScript side of things but thought it would be good to report it.
