Build failure under Termux: can not execute sklearn/_build_utils/version.py

### Describe the bug

When attempting to install the newest (and older) versions of scikit-learn-1.6.dev0 using regular pip install, the installation fails due to a missing version.py file. This issue occurs on an Android system using Termux.
Environment details:
OS: Linux localhost 4.14.186+ (Android)
Architecture: aarch64
Python: 3.11
The error occurs during the Meson build process, which tries to execute a non-existent file:
/data/data/com.termux/files/home/downloads/scikit-learn/sklearn/_build_utils/version.py
A workaround patch has been developed to address this issue:
```
#!/bin/bash

# Navigate to the scikit-learn directory, e.g.:
cd ~/downloads/scikit-learn

# Extract version from pyproject.toml and remove "dev" suffix
VERSION=$(grep 'version =' pyproject.toml | sed 's/version = "\(.*\)"/\1/' | sed 's/\.dev0//')

# Create the directory if it doesn't exist
mkdir -p sklearn/_build_utils

# Create the version.py file with the correct content
cat << EOF > sklearn/_build_utils/version.py
#!/usr/bin/env python
print('${VERSION}')
EOF

# Make the file executable
chmod +x sklearn/_build_utils/version.py

echo "Created sklearn/_build_utils/version.py with version ${VERSION}"
```
This patch:
- Extracts the version number from pyproject.toml
- Removes the "dev" suffix
- Creates the missing version.py file with a generic Python shebang
- Makes the file executable

After applying this patch, the Meson build process completes successfully, and the installation can proceed:

OK, trying your experiment then - unistalling yet again and `pip install scikit-learn==1.4.2 -v` ...
