refactor(sandbox): remove network mode validation for CODE_INTERPRETE…

[OhYee]

…R template type

Removed the validation logic that prevented CODE_INTERPRETER and AIO template types from using PRIVATE network mode, as this restriction is no longer needed.

移除了阻止CODE_INTERPRETER和AIO模板类型使用PRIVATE网络模式的验证逻辑，因为此限制不再需要。
