chore: add devcontainer.json (#1810)

- to enable vscode users to just open the dev container and have them be ready to go in minutes
- the config follows https://github.com/podkrepi-bg/dev-containers/blob/main/nodejs/README.md
- and pushes to the next version 1.2.0 which fixes the vscode unsupported alpine image error
