chore: 移除devcontainer轻量环境的部分非必要依赖 (#14499)

对 devcontainer 的改动如下：
1. 在轻量环境中，
   - 移除 `python` 及其相关格式化扩展 `black` 和 `isort`
   - 移除 `black` 和 `isort` 等 pip 包
2. 在所有环境中，
   - 将 VS Code 的默认主题设置为 `Default Dark Modern`

* chore: 移除devcontainer轻量环境的部分非必要依赖

* chore: 将编辑器默认颜色主题调整为暗色

* chore: 将空白环境的post-create脚本独立，与其它环境一致

* chore: 把maa扩展加回来
