Fix browser test errs on mac

[allison-truhlar]

Addresses issue https://github.com/google/neuroglancer/issues/627.

• Adds playwright as a dependency; removes webdriverio.
• Configures Vitest to use playwright as the browser provider rather than webdriverio.
• Adds npx playwright install to the test and test:watch commands in package.json. This is to ensure playwright updates after the initial install, to avoid getting the error Error: browserType.launch, followed the by the instructions: "Looks like Playwright Test or Playwright was just installed or updated. Please run the following command to download new browsers: npx playwright install.

All tests pass in macOS 14.5 using this configuration.

Thanks!

Does this allow the WebGL tests to pass in Github actions on macOS? (See https://github.com/google/neuroglancer/commit/33f5eb5e4ceef81d221436764bbdc438724abbcd#diff-5c3fa597431eda03ac3339ae6bf7f05e1a50d6fc7333679ec38e21b337cb6721)

I'm not sure - I just removed the if statement in the GitHub action to allow the tests including WebGL to run.

It looks like this still does not allow the tests to pass on macOS on github actions, but hopefully it will work in the future after https://github.com/microsoft/playwright/issues/30585 is fixed.

Per the description here (https://playwright.dev/docs/library#key-differences) does it work to just add @playwright/browser-chromium as a dev dependency rather than having to do npx playwright install?

[allison-truhlar]

In the latest commit, I tested adding @playwright/browser-chromim as a dev dependency and removing npx playwright install from the test commands - I can confirm this works.

Error: browserType.launch: Executable doesn't exist at /Users/runner/Library/Caches/ms-playwright/chromium-1124/chrome-mac/Chromium.app/Contents/MacOS/Chromium

Would adding npx playwright install-deps chromium help resolve the client tests here?

[allison-truhlar]

@mkitti Which version of the PR did you get this error from? Is this after I added @playwright/browser-chromium as a dev dependency?

[mkitti]

Yes. You can see it in the Github Actions tests for client (macos-latest): https://github.com/google/neuroglancer/actions/runs/10289555738/job/28497954784?pr=630#step:14:18

[allison-truhlar]

Added npx playwright install-deps chromium to the workflow, per @mkitti's suggestion, to see if this resolves the test failure in GitHub actions.
