feat(singbox): Support network=tcp in VMESS/VLESS

[cnsunyour]

singbox 的 vmess/vless 节点不用必须指定 transport ，也就是 surgio 里的 network 可以是默认值 tcp 。 我的 server 端用 singbox 配置的 vless+vision+reality 节点，本地修改后测试连接成功。 不过没有 vmess 节点，因此只测试了 vless ，并未测试 vmess ，只是根据文档中描述 transport 为非必须项，

感谢共享代码。之前Singbox的支持也是社区贡献的，可能遗漏了这个点。麻烦可以顺便看看测试用例吗？

好的，我修改后生成的 singbox 配置的 vless 节点是这样：

    {
      "type": "vless",
      "tag": "自建A2",
      "server": "www.example.com",
      "server_port": 12345,
      "uuid": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      "flow": "xtls-rprx-vision",
      "tls": {
        "enabled": true,
        "utls": {
          "enabled": true,
          "fingerprint": "chrome"
        },
        "reality": {
          "enabled": true,
          "public_key": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
          "short_id": "xxxxxxxxxxxxx"
        },
        "server_name": "www.example.com"
      }
    }

对应的 surgio provider 配置是这样：

    {
      nodeName: "自建A2",
      type: "vless",
      hostname: "www.example.com",
      method: "none",
      network: "tcp",
      port: 12345,
      uuid: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      flow: "xtls-rprx-vision",
      sni: "www.example.com",
      udpRelay: true,
      clientFingerprint: "chrome",
      realityOpts: {
        shortId: "xxxxxxxxxxxxx",
        publicKey: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
      }
    }

可以修改一下用例吗，通过 CI 就能合并了

噢噢，我试着改一下。抱歉之前没理解意思。
