Using {:system, "AWS_ROLE_ARN"} causes a crash

### Setup
Erlang/OTP 25 [erts-13.2.2.9] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1]
Elixir 1.14.5 (compiled with Erlang/OTP 25)

### Behavior
Based on the following configuration provided in the 2.3 documentation:
```
config :ex_aws,
  access_key_id: [{:awscli, "default", 30}],
  secret_access_key: [{:awscli, "default", 30}],
  awscli_auth_adapter: ExAws.STS.AuthCache.AssumeRoleCredentialsAdapter,
  awscli_credentials: %{
    "default" => %{
      role_arn: {:system, "AWS_ROLE_ARN"},
      access_key_id: {:system, "AWS_ACCESS_KEY_ID"},
      secret_access_key: {:system, "AWS_SECRET_ACCESS_KEY"},
      source_profile: "default"
    }
  }
```

### Expected behavior
`assume_role_request` params should contain a well-formed `role_arn`, not a tuple.

### What happens
The library currently keeps the role_arn as-is in the AWS query:
```
%ExAws.Operation.Query{
  path: "/",
  params: %{
    "Action" => "AssumeRole",
    "DurationSeconds" => 900,
    "RoleArn" => {:system, "AWS_ROLE_ARN"},
    "RoleSessionName" => "default_session",
    "Version" => "2011-06-15"
  },
  content_encoding: "identity",
  service: :sts,
  action: :assume_role,
  parser: &ExAws.STS.Parsers.parse/2
}
```

Resulting in this stacktrace:
```
