Better support for non-x86-64 archs

Firstly, thanks for this awesome template! I'm pretty new to Next, so I'm sorry if this isn't a very good issue.

I believe that the `mcr.microsoft.com/devcontainers/universal:2` image used in this template is only built for `x86-64` arch according to https://github.com/microsoft/vscode-dev-containers/tree/main/containers/codespaces-linux. I'm guessing this is going to run into many performance issues for `amd64` users like me on Apple silicon.

I found a simple change like this seems to at least work enough for a template: https://github.com/github/codespaces-nextjs/compare/main...myyk:codespaces-nextjs:patch-1 (pls excused the misleading comment on it and the bad formatting)

I don't know if there are other reasons why `devcontainers/universal` was used instead of `devcontainers/typescript-node` though.

首先检查模板的 devcontainer 配置以及 `mcr.microsoft.com/devcontainers/universal:2` 镜像声明。将其与链接的补丁进行比较，并检查 `devcontainers/typescript-node` 是否在不丢失模板现有要求的情况下提供所需的架构支持。模板能够在非 x86-64 系统上正常工作，并且镜像选择已有文档说明或经过验证，即表示完成。
