[Feature Request]: Migrate acceptance tests for voiceover-submitter from Puppeteer to Playwright

Is your feature request related to a problem? Please describe.

The voiceover-submitter acceptance test specs still run on Puppeteer. As part of the broader migration (https://github.com/oppia/oppia/issues/24715), these need to move to Playwright so we can retire Puppeteer entirely from the acceptance test suite.

Describe the solution (or solutions) you'd like

Migrate the following specs from core/tests/puppeteer-acceptance-tests/specs/voiceover-submitter to core/tests/playwright-acceptance-tests/specs/voiceover-submitter, following our existing Playwright conventions:

• create-delete-and-update-status-of-voiceovers-of-the-explorations.spec.ts

At a high level, this involves:

1. Removing the old spec from puppeteer-acceptance-tests/specs/voiceover-submitter and adding a rewritten version to playwright-acceptance-tests/specs/voiceover-submitter, in Playwright syntax/conventions.
2. Updating the framework field for each suite in acceptance.json to "playwright".
3. Adding any missing utility methods to playwright-acceptance-tests/utilities.
4. Verifying tests pass locally, both desktop and mobile:
   • Desktop: python -m scripts.run_acceptance_tests --suite={suite_name}
   • Mobile: python -m scripts.run_acceptance_tests --suite={suite_name} --mobile
   • Videos for both runs will be generated in the oppia_full_stack_test_video_recordings folder (sibling directory to the Oppia root)
   • Traces for both runs will also be generated in the oppia_full_stack_test_playwright_results folder (sibling directory to the Oppia root)
5. Running the stress test on your fork, on the branch you want to merge, using the stress_test_acceptance_test.yml workflow, for 200 total runs (100 desktop + 100 mobile), to rule out flakiness before requesting assignment.
6. Share the stress test link and either the trace or video in the issue thread.

After reviewing the stress test run and video/trace recordings we can assign you to the particular spec file.
