bump python version to 3.12 in dev container

[yp05327]

The default version is 3.9.2, which is not supported by poetry.

Bump it to 3.12 if possible, that's what we use on CI.

Please test it.

Tested the build process and postCreateCommand. It works well.What others should I test?

ps: As I know, dev container image can be built and run by cli command(https://github.com/devcontainers/cli), so maybe it is possible to test it in ci.

All good, I was just worried 3.12 might not be available yet.

How fast does it build?

How fast does it build?

I think this is based on the spec and the speed of the internet.
And it wouldn't be fast, as docker build is always slow IMO.

But we don't need to test it every time, only on the config changed, and that won't be too often.
Maybe we can consider it later, when it becomes important enough to do it.

[silverwind]

Yeah, sounds plausible to run it only when the config changed via files-changed. If it's fast enough (I'd say sub 2 minutes), also add pyproject.toml, package.json and go.mod to dependencies.
