Remove tests directory to fix dependabot errors

[IndiraBiswas]

This PR removes the entire tests directory from the repository.

Why is this change necessary?

The tests folder contains outdated dependencies (specifically Playwright test dependencies) that have triggered multiple security vulnerabilities (1 critical, 3 high, 1 moderate) flagged by Dependabot. Since these tests are no longer actively maintained or executed, removing the folder is the safest and most efficient way to resolve the security alerts without impacting the core plugin functionality.
