Connect Backstop to sauce labs

Hi Team,

I have successfully installed the BackstopJS application locally and am looking to connect it with Sauce Labs. I am using Playwright as the engine instead of the default Puppeteer. Despite extensive searching, I have not found a clear way to achieve this connection. Could you please guide me on how to connect BackstopJS with Sauce Labs using Playwright?

Here is the content of my package.json:
```
"devDependencies": {
"@playwright/test": "^1.30.0",
"backstopjs": "^6.3.25",
"puppeteer": "^24.2.1"
},
"dependencies": {
"playwright": "^1.50.1"
}
```
