This PR adds a clearOnError option to the password prompt to enforce typing the whole password again on an error. This is particularly useful when mask: '' (i.e. a hidden input) is given.

e.g. Consider this case

const pw = await prompt.password({
  message: 'Please enter your password:',
  mask: '',
  validate: (val) => val === 'test123' ? undefined : 'Password must be "test123"'
});

If the user enters "password" and hits return, an (expected) error Password must be "test123" will appear, like so:

The user then enters "test123" and hits return. They will get the same error because the value is actually "passwordtest123" which is not apparent with a hidden input.

This PR adds a clearOnError boolean option to have the input clear out after an error to avoid the confusion above.
