test: refactor tests for Tag component

[adaex]

This pull request enhances the test coverage for the Tag and Tag.List components in packages/arcodesign/components/tag/__test__/index.spec.js. It introduces new test cases to verify component behavior under various scenarios, including mounting/unmounting, event handling, style rendering, and edge cases. Additionally, it improves the organization and clarity of the test descriptions by adding comments in both English and Chinese.

Enhancements to Tag component tests:

• Replaced individual mount tests with a consolidated test to verify mounting and unmounting behavior across different props.
• Added tests for click event handling, including tag click and close button click, with mock functions to validate callbacks.
• Expanded style rendering tests to include various combinations of props like type, size, filleted, halfBorder, and custom colors.
• Introduced tests for rendering icons and handling the closeable property, ensuring proper display and behavior.

Addition of Tag.List component tests:

• Added tests for padding configuration, verifying both string and numeric values for vertical and horizontal padding.
• Implemented tests for the add button functionality, including default, custom, and hidden add button scenarios.
• Verified tag interactions, styling inheritance, and custom styles, including handling of closeable tags and edge cases like empty lists.

• Ensure that 'prefix' is defined or imported in this test file to make the test self-contained.

expect(container1.querySelector(`.${prefix}-primary`)).toBeInTheDocument();

packages/arcodesign/components/tag/test/index.spec.js:150

• Confirm that 'defaultContext' is available in the test scope or imported correctly to prevent reference errors.

const listElement1 = container1.querySelector(`.${defaultContext.prefixCls}-tag-list`);
