Fix release pipeline publish failures due to missing poetry repository config

[Copilot]

Release pipeline was failing during publish stage with "Aborted!" because poetry couldn't resolve repository references (-r testpypi, -r pypi) in GitHub Actions environment.

Changes

• Add TestPyPI repository configuration step before publish to configure https://test.pypi.org/legacy/
• Add PyPI repository configuration step before publish to configure https://upload.pypi.org/legacy/
• Remove redundant --build flags from publish commands since packages are already built in prior step
• Use explicit repository references for both TestPyPI and PyPI for consistency

# Before: Failed silently
poetry publish -r testpypi --build -u __token__ -p "$TOKEN" --no-interaction

# After: Configure repo first, remove redundant build
poetry config repositories.testpypi https://test.pypi.org/legacy/
poetry publish -r testpypi -u __token__ -p "$TOKEN" --no-interaction

Added explicit PyPI repository configuration step for the production job for consistency with the TestPyPI configuration. The workflow now configures both repositories before publishing. Changes in commit 7daaebf.
