[Bug] Routing rules not respected for /.auth suffix

**Describe the bug**

I'd like to enable only one auth provider and disable all others. For that I'm using this `staticwebapp.config.json`:

```json
{
"routes": [
{
"route": "/.auth/login/github",
"statusCode": 200
},
{
"route": "/.auth/login/*",
"statusCode": 404
}
]
}
```

This basically tell that the GitHub route is fine, while all other should return a 404.
This works perfectly locally using SWA CLI, but when deployed on SWA it's completely broken:

- `/.auth/login/github` just results in a blank page (only status 200 was returned...)
- Any other auth providers works as usual!

**Expected behavior**
GitHub auth provider works, and other providers returns a 404 error.

**Additional context**
Routes likes these (expection first, then using a wildcard to set a common rules for the rest a path) works with any other hosts like Netlify, Vercel, etc. The fact that it works as expected with the SWA CLI is also a good sign that `/.auth/` routes should be processed just like the rest.
