feat(build-project): rewrite script entries when using custom top namespace

[DavidVujic]

Description

Rewrite the entries in [tool.poetry.scripts] with a top namespace, when passing in the --with-custom-namespace option for poetry build-project.

Motivation and Context

Requested in DavidVujic/python-polylith#178

This will make the build-project more flexible and not assume that the custom top namespace have been added manually in the pyproject.toml file for a CLI script entry.

How Has This Been Tested?

✅ CI
✅ Added unit tests for the TOML generation.
