Playwright traces render as zip download instead of embedded trace viewer

[antonfilichkin]

What happened?

When attaching a Playwright trace via AllurePlaywright.attachTrace(...), the resulting Allure attachment is tagged with the generic application/zip content type. Because of this, the Allure report shows the trace as a plain zip file to download, instead of using Allure's built-in embedded Playwright trace viewer.

Steps to reproduce

1. Use AllurePlaywright.startTracing(...) / attachTrace(...) in a test.
2. Run the test and generate the Allure report.
3. Open the report and view the trace attachment.

Expected behavior
The trace attachment opens in Allure's embedded trace viewer.

Actual behavior
The attachment is offered as a generic zip file download.
