Pull request overview

This pull request improves the Playwright browser installation process in the E2E test workflow by removing redundant system dependency installation steps and enhancing exit code handling. The PR addresses debugging issues identified during E2E CI browser installation.

Changes:

• Removed redundant npx playwright install-deps commands that were unnecessary since npx playwright install --with-deps already installs system dependencies
• Fixed exit code handling by capturing the installation command's exit status in a variable before subsequent commands
• Added explicit exit $EXIT_CODE to ensure installation failures properly propagate and fail the workflow step
