Azure Static Web App allowedForwardedHosts wildcard domain error

Azure Static Web App does not support wildcard custom domains, so i tried to add a CDN front door so that i can use wildcard domains, but i cannot add a wildcard domain to allowedForwardedHosts inside staticwebapp.config.json.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to 'staticwebapp.config.json'
2. Append:
```
"forwardingGateway": {
"allowedForwardedHosts": [
"*.domain.com"
]
}
```
4. Push to git to activate the publish action

Error:
*.domain.com is not a valid value for a host in allowedForwardedHosts.

- staticwebapp.config.json file:
```
{
"trailingSlash": "auto",
"navigationFallback": {
"rewrite": "index.html",
"exclude": ["/images/*.{png,jpg,gif}", "/css/*", "/js/*"]
},
"forwardingGateway": {
"allowedForwardedHosts": [
"*.domain.com"
]
}
}
```

**Expected behavior**
To either Azure Static Web App support wildcard domains or allow us to use CDN front door to have a wildcard domain.
