bin/python size exploded 2000 times larger

Is there a reason why the binary bin/python3.10 in latest python 3.10.19 has size 43963640 which is more than 2000 times larger than bin/python3.10 in python 3.10.15 (size 20944)?

```
python = use_extension("@rules_python//python/extensions:python.bzl", "python")
python.toolchain(
is_default = True,
python_version = "3.10.15",
)
```

Start by comparing the bin/python3.10 artifacts produced for Python 3.10.15 and 3.10.19, using the versions and sizes reported in the issue. Read the shown python.toolchain configuration and inspect how the selected toolchain packages the binary. Done means identifying the source of the size increase and recording a confirmed cause or required follow-up.
