Add instructions on connect page to avoid `server does not allow insecure connections, client must use SSL/TLS` error

After creating a deployment and trying to connect to it with a connection string and a golang mysql client, I received the following error:
```
Error 1105: unknown error: Code: UNAVAILABLE
server does not allow insecure connections, client must use SSL/TLS
```

The solution here was to add `tls=skip-verify` to the connection string as a query parameter. This should be documented on the connection page so that other's can quickly connect to their instances.
