Change DAB's default authentication provider

[JerryNixon]

What?

Today, when a developer uses the CLI command dab init without explicitly supplying the authentication provider, the default value used is StaticWebApps. Change this default to Custom.

How to explicitly supply the authentication provider

dab init  --auth.provider StaticWebApps
dab init  --auth.provider AppService
dab init  --auth.provider EntraId
dab init  --auth.provider Custom

Showing the authentication provider in DAB's configuration

{
  "runtime": {
    "host": {
      "authentication": {
        "provider": "AppService" 
      }
    }
  }
}

Why?

Because the (preview) Database Connection feature of Static Web Apps is likely to be deprecated; it makes no sense to keep StaticWebApps as DAB's default provider. This does NOT mean we would stop supporting this provider, only change the default provider.
