ci: add test package publishing workflow

Add automated test package publishing job that runs on all branch pushes after tests pass.
This creates a test version of the package with an incremented patch version and publishes it to npm with the 'test' tag.

The workflow includes steps to determine the next version, update package.json with a test package name,
build the package, and publish it as a test version for verification purposes.

ci: 添加测试包发布工作流

添加自动化测试包发布作业，在所有分支推送且测试通过后运行。
这会创建一个具有递增补丁版本的测试包，并将其以 'test' 标签发布到 npm。

该工作流包括确定下一个版本的步骤，使用测试包名称更新 package.json，
构建包，并将其作为测试版本发布以供验证。
