Doc: Clarify UUID bytes attributes

[savagemechanic]

Docs-only change.

Clarifies UUID.bytes and UUID.bytes_le wording by describing those values as 16-byte bytes objects rather than byte strings.

Local checks:

make -C Doc check SPHINXOPTS='-W --keep-going'
python3 -m py_compile Lib/uuid.py

Thanks for the PR, this is more precise. In particular the changed example in the docstring (the old UUID(bytes='\x12\x34\x56\x78'*4) would fail with an error).
