[Bug] WebSocket infinitely retries when server returns invalid protocol

### Component

provider, pubsub

### What version of Alloy are you on?

1.7.3

### Operating System

None

### Describe the bug

In this scenario, it retries indefinitely and the error cannot be caught:

1. The WebSocket server is available and connects normally.
2. After a successful connection, it returns a different protocol.

RPCs to reproduce：

- wss://rpc.garnetchain.com
- wss://bahamut-rpc.publicnode.com
- wss://echo.websocket.org

Code to reproduce the issue：
```rust
use alloy::network::AnyNetwork;
use alloy::providers::{Provider, ProviderBuilder, RootProvider, WsConnect};
use alloy::rpc::client::RpcClient;
use anyhow::Result;
use tracing::{debug, error, info};

#[tokio::main]
async fn main() -> Result<()> {
tracing_subscriber::fmt()
.with_max_level(tracing::Level::DEBUG)
.init();

let rpc_url = "wss://bahamut-rpc.publicnode.com";
debug!("Connecting to RPC: {}", rpc_url);

let ws_connect = WsConnect::new(rpc_url).with_max_retries(2);
let rpc_client = RpcClient::builder().ws(ws_connect).await?;

let provider: RootProvider = ProviderBuilder::default().connect_client(rpc_client);

info!("Connected to RPC successfully");

match provider.get_block_number().await {
Ok(block) => info!("Block: {}", block),
Err(err) => {
error!("{}", err);
}
}

Ok(())
}
```

Output:
