Update Library Document Set Welcome Page View using Playwright and Azure Function

1. This is using Playright which is pretty new and maintained by Microsoft.
2. This uses a Linux NodeJs Azure Function so you will have to use Visual Studio or Visual Studio code to deploy.
3. This was made to faciliate pnp/pnpframework#105 till there is a proper solution from the PnP Framework.

Things to note

1. If you are using VS Code ensure your .vscode/settings.json has "azureFunctions.scmDoBuildDuringDeployment": true
2. Ensure Azure Function has "PLAYWRIGHT_BROWSERS_PATH" :0 in its function app settings. Remove this if you are testing locally.
3. Navigate to /home/site/wwwroot and run npm install and npm install playwright-chromium. I had it failed on me when playwright-chromium didn't get installed as part of the package.json.
4. This require a SharePoint Admin account providing username and password to Playwright to get access to the required page as SharePoint isn't an anonymous access system. So it is advisable to create a separate account or update to use Azure KeyVault
