Automate the release pipeline.

[trivialfis]

At the moment, creating a PyPI release is a very manual process.

For Windows, I need to download the wheel from the GA CI, upload it to test PyPI, install the uploaded wheel using pip install -i for testing, then upload it to the real index.

For Linux, I used a local Docker cluster for multi-arch build and created and audited the wheel using different workers.

todos:

• Automate the Linux image build process using GA.
• Automate the wheel audit and twine check.
• Automate the upload to the test index.
• Automate the upload to the real index.
• Ensure PyPI can verify project links

prs:

• Use base image for building release package. #39
• [CI] Action for creating release wheels. #38
• [ci] Build sdist. #40
