CI: publish to pypi.org and github via tag, release CI part 3

[Zeroto521]

closes #10

[Zeroto521]

The final step to publish pakcage.

[Zeroto521]

total release CI:

1. create a tag (prefix with v, i.e. v0.1) in local or upstream
2. tag event triggers release.yaml github action
3. release.yaml will build packages and push to github release page and pypi.org

Notes:

• If a tag contains rc (i.e. v0.1rc1), release.yaml will mark this tag as a prerelease package.
• All packages released to github release page, its status will be marked as a draft. In the meantime, we could add changelogs.
