New auth method type aws-iam not visible on the UI

Hello i made a fresh install of consul (with ACLs enabled) on AWS EKS with the official helm chart.

Everything works fine, i am trying now to create a new auth method.

I did :

```
consul acl auth-method create -type aws-iam \
-name iam-role-login \
-config='{
"BoundIAMPrincipalARNs": ["arn:aws:iam::123456789012:role/MyRoleName"],
"EnableIAMEntityDetails": true,
"IAMEntityTags": ["consul-namespace"],
"ServerIDHeaderValue": "consul.mydomain.com",
"MaxRetries": 3,
"IAMEndpoint": "https://iam.amazonaws.com/",
"STSEndpoint": "https://sts.us-east-1.amazonaws.com/",
"AllowedSTSHeaderValues": ["X-Extra-Header"]
}'
```

And after i did a binding rules :

```
consul acl binding-rule create -method 'iam-role-login' \
-description 'Binding Rule for consul-consul-client' \
-bind-type 'role' \
-bind-name 'consul-consul-client-acl-role' \
-selector 'entity_name=="myRoleName"'
```

After that when i try to Log In via the UI i don't see the auth method that i created i just the Log in with token method, do you know how to see the new auth method from the UI so i can use it ?

Thanks a lot !

Start by reproducing the reported setup with the `consul acl auth-method create` and `consul acl binding-rule create` commands, then inspect the Consul UI login entry point. Verify whether the created `aws-iam` method is discovered and rendered alongside token login; done means the cause of its absence is identified and the method is available in the UI.
