[docs] [issue11310] Document byte[s|array]() and byte[s|array](count) in docstrings

[Terry J. Reedy]

New submission from Terry J. Reedy <tjreedy at udel.edu>:

The entry for bytearray(source...) says
"
The optional source parameter can be used to initialize the array in a few different ways:
...
If it is an integer, the array will have that size and will be initialized with null bytes. 
...
Without an argument, an array of size 0 is created.
"
[integer must be non-negative -- patch adds this]
The entry for bytes(source...) refers back to the bytearray entry.

The docstrings for bytes and bytearray omit both possibilities.
Attached is a possible patch to include them.
