Standardize spelling: "writeable" → "writable" in library docs

Python's own io module uses "writable" (e.g. IOBase.writable()), and
the codebase overwhelmingly prefers this spelling (33 vs 11 in docs,
55 vs 3 in source). Standardize the remaining "writeable" instances in
library documentation to match.

Affected files: io.rst, marshal.rst, subprocess.rst, ssl.rst,
ctypes.rst, functions.rst, zipfile.rst
