Bump ison-py, ison-cpp and isonantic-cpp to their release versions

The version freeze lifted once the parity and C# work was pushed. These three
were the only packages whose metadata still trailed their CHANGELOG head:

  ison-py         1.0.3 -> 1.0.4
  ison-cpp        1.0.1 -> 1.0.2
  isonantic-cpp   1.0.0 -> 1.0.1

Each version appears in more than one place, so all of them move together:
pyproject.toml and __version__ for Python, CMakeLists.txt plus the header's
VERSION constant and @Version doc tag for the C++ packages. ison-cpp's header
constants were already at 1.0.2 while CMakeLists said 1.0.1, so this also
resolves that drift.

ison-py's module docstring had a stale "Version: 1.0.1" that had not tracked
__version__ for two releases; it now matches.

All 11 packages now satisfy metadata == CHANGELOG head, which is what
release-all.yml's preflight gates on. Verified: ison-py 233 passed, ison-cpp
2/2, isonantic-cpp 1/1.
