missing error message `bytes(negative number)`

[TG-Techie]

I was messing around in python, for fun, and noticed that there was no error message for trying to make a bytes instance of a negative number. instead of saying 'ValueError: cannot convert negative number to bytes' it just raises 'ValueError:'.

this is copied from the repl on mu.

>>> bytes(-5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError:

MicroPython (and by inheritance also CircuitPython) has many places where it throws exceptions without error messages, or re-uses more generic error messages than regular Python has. This is a trade-off, necessary to keep the binary small. It seems to me that in this particular case it's relatively easy to realize what the reason for the error is.

I agree with @deshipu. No extra error message is needed here for now.
