Add Playwright E2E tests for Indexing Policy (#2358)

* Initial plan

* Add Playwright test for Indexing Policy

Co-authored-by: sakshigupta12feb <206070758+sakshigupta12feb@users.noreply.github.com>

* Refactor Indexing Policy test to use Editor helper class

Co-authored-by: sakshigupta12feb <206070758+sakshigupta12feb@users.noreply.github.com>

* Address code review feedback - add helper function and improve editor handling
