shiv version 1.0.4 reports the incorrect version of 1.0.3

I installed `shiv` with `pip` and noticed the version, published as 1.0.4, was reported to be 1.0.3 via `shiv --version`. This is reproducible following the steps for developing in the Readme. Ultimately, the `__version__` needs to be changed in `src/shiv/cli.py`. I considered a Pull Request for this issue, but settled on a bug report in case there are other changes in progress that would make a pull request bumping the version moot.

Below find all the output from the build process, but here is the piece highlighting the issue:
```

The issue identifies src/shiv/cli.py as the location of the incorrect __version__ value. Start by following the README development build steps and inspect how shiv --version obtains its value. Done means an installed 1.0.4 build reports shiv, version 1.0.4.
