devcontainer用のDockerfileを更新：poetryのインストールで失敗しないようにした

[yuji38kwmt]

概要

現状のDockerfileだと、poetryのインストールで以下のエラーが発生したため、修正した。

The virtual environment was not created successfully because ensurepip is not available.  On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.

以下、実行ログ。
