Closes https://github.com/mitodl/ocw-hugo-themes/issues/1279

Description (What does it do?)

The "Transcripts start time matches video start time" test in video.spec.ts loads a video that started refusing to play in the Chromium browser, which Playwright uses on the backend to run its tests. This PR switches out the Chromium browser for Google Chrome and Firefox, which seem to run the test fine.

How can this be tested?

• Check out this branch locally
• Make sure you don't have any values in your .env that would cause the end to end tests to fail. It may be best to back up your .env and run the tests with an empty one so it uses the defaults.
• Run yarn test:e2e and verify that the tests pass

@ibrahimjaved12 I reverted this PR to use the original video from the test and swapped out the browsers being used for testing, since Chromium is being problematic with videos.

We decided that we will deal with those playwright tests separately in a different ticket(s) - because the purpose of this PR is to pass the currently failing CI test. And this PR does that - it's safe to deploy it as those locally failing playwright tests are specifically because of Mac OS being used with firefox.
