Consider improving the output of the `--help` option for boolean arguments in Q# standalone executables

[cesarzc]

Using the --help option when running a Q# standalone executable results on the following text for a program with a single entry-point operation that receives Int, Pauli and Bool arguments:

Usage:
  Sample.RandomBit [options] [command]

Options:
  --number-of-bits <number-of-bits> (REQUIRED)
  --my-cool-pauli <PauliI|PauliX|PauliY|PauliZ> (REQUIRED)
  --my-cool-bool (REQUIRED)
  -s, --simulator <simulator>                                 The name of the simulator to use.
  --version                                                   Show version information
  -?, -h, --help

In this output, it is unclear why a boolean option like --my-cool-bool is required.

Updating the output for --my-cool-bool option to the following would clarify this:

--my-cool-bool <true|false> (REQUIRED)
