docs: stop talking about the .well-known/matrix/client changes

These were relevant on an old version of the specs, and just confuses people.

 At time of writing, the authentication service is meant to be run on a standalone domain name (e.g. `auth.example.com`), and the homeserver on another (e.g. `matrix.example.com`).
 This domain will be user-facing as part of the authentication flow.
 
-When a client initiates an authentication flow, it will discover the authentication service through the deployment `.well-known/matrix/client` endpoint.
-This file will refer to an `issuer`, which is the canonical name of the authentication service instance.
-Out of that issuer, it will discover the rest of the endpoints by calling the `[issuer]/.well-known/openid-configuration` endpoint.
-By default, the `issuer` will match the root domain where the service is deployed (e.g. `https://auth.example.com/`), but it can be configured to be different.
-
 An example setup could look like this:
 
   - The deployment domain is `example.com`, so Matrix IDs look like `@user:example.com`
-  - The issuer chosen is `https://auth.example.com/`
-  - The homeserver is deployed on `matrix.example.com`
   - The authentication service is deployed on `auth.example.com`
-  - Calling `https://example.com/.well-known/matrix/client` returns the following JSON:
-
-    ```json
-    {
-      "m.homeserver": {
-        "base_url": "https://matrix.example.com"
-      },
-      "org.matrix.msc2965.authentication": {
-        "issuer": "https://auth.example.com/",
-        "account": "https://auth.example.com/account"
-      }
-    }
-    ```
-    
-  - Calling `https://auth.example.com/.well-known/openid-configuration` returns a JSON document similar to the following:
-
-    ```json
-    {
-        "issuer": "https://auth.example.com/",
-        "authorization_endpoint": "https://auth.example.com/authorize",
-        "token_endpoint": "https://auth.example.com/oauth2/token",
-        "jwks_uri": "https://auth.example.com/oauth2/keys.json",
-        "registration_endpoint": "https://auth.example.com/oauth2/registration",
-        "//": "..."
-    }

+  - The homeserver is deployed on `matrix.example.com`
 
 With the installation planned, it is time to go through the installation and configuration process.
