Add .vscode config files to better integrate with Azure Static Web Apps extension

[alexweininger]

👋

My name is Alex and I'm working on adding better support for templates in the Azure Static Web Apps VS Code extension.

This PR has two additions:

1. Adding staticWebApps.outputSubpath setting with a value of dist/angular-basic in .vscode/settings.json

This addition makes it so that users can accept the default configurations when deploying this template via the Azure Static Web Apps VS Code extension. Adding the setting allows us to prefill the prompt with the correct configuration for this template. Before now, if the user selected the defaults then the template would fail to build once pushed/deployed to GitHub/Azure. Which is a really terrible 😢 experience for new users that we'd love to prevent.

• Build presets should work with Quickstart templates microsoft/vscode-azurestaticwebapps#453
• Should the pre-fill selections assume the root? microsoft/vscode-azurestaticwebapps#277 (comment)

2. Adding ms-azuretools.vscode-azurestaticwebapps to recommended extensions in .vscode/extensions.json

More details about what we are planning for the "Create from template" feature in our extension:

• Create and deploy SWA from template without reloading VS Code microsoft/vscode-azurestaticwebapps#452
