chore: update devcontainer configuration

[openscript]

Changes

It seems like the dev container configuration has not been touched for a long time. It is not compatible with the current environment. A more modern configuration representing the same environment (Go 1.22, pnpm, node 24) like in the ci has been set.

Testing

No tests needed for setting up dev containers.

Docs

No documentation needed, it's for Astro compiler development only and for contributors there is no change to the previous state.
