Using logLevel and releaseMode from the sample module in docs returns error

[carlosedp]

If setting a new Scala Native project using the sample provided by https://com-lihaoyi.github.io/mill/mill/Common_Project_Layouts.html#_scala_native_modules, the following error is returned:

/riscvassembler/build.sc:65: not found: value ReleaseMode
  def releaseMode = T(ReleaseMode.ReleaseFast) // optional
                      ^
/riscvassembler/build.sc:64: not found: value NativeLogLevel
  def logLevel    = T(NativeLogLevel.Info)     // optional
                      ^
/riscvassembler/build.sc:64: `T.command` definitions must have 1 parameter list
  def logLevel    = T(NativeLogLevel.Info)     // optional

The import mill.scalanativelib.api._ is missing in the example.
