Swap dependency installation in CI

The `npx playwright install --with-deps` command was producing this warning:

```
WARNING: It looks like you are running 'npx playwright install' without first
installing your project's dependencies.
```

so this change addresses that by running `npm ci` before running
`npx playwright install --with-deps`.
