Added ability to pass arguments to the Playwright browser (#13146)

- **Description:** Enhanced `create_sync_playwright_browser` and
`create_async_playwright_browser` functions to accept a list of
arguments. These arguments are now forwarded to
`browser.chromium.launch()` for customizable browser instantiation.
  - **Issue:** #13143
  - **Dependencies:** None
  - **Tag maintainer:** @eyurtsev,
  - **Twitter handle:** Dr_Bearden
