webgpu: Switch back to old karma reporter (#7449)

With karma-jasmine-html-report, we don't know how many cases are
skipped. The result looks like below:
TOTAL: 37 SUCCESS

The old report provides more info as below:
Chrome 113.0.0.0 (Windows 10): Executed 37 of 4559 (skipped 4522) SUCCESS (1.045 secs / 0.395 secs)

This PR also fixes a comment typo in setup_test.ts
