Add newest idris tool chain support

[weihongliang233]

Great work, but when opening the project in vscode devcontainer, the following error occured.

Currently, the docker image uses idirs2, while the vscode extension installed seems not support idris2 and it's an old project (last commit 7 years ago).

Is there any plan to upgrade the project to use newest idirs2 compiler and newest vscode extension?
