Packages/node upgrade and devcontainer for vscode

[afonsonf]

Upgraded node and updated packages:

• node 12.12.0 -> 18.15.0
• vscode-tmgrammar-test options changed, -s and -t were deprecated: https://github.com/PanAeon/vscode-tmgrammar-test/releases/tag/v0.1.1
• Some lint warnings fixes
• Small code fixes because the updated packages

Add support to vscode dev container:

• There was already a config for codespaces however it did not work for local dev container with vscode
• Move to typescript-node:18 as the base image for the dev container
• Add a dockerfile for the package instalation to be cached as a image layer and not run every time the a dev container is open
• Some documentation on its usage

Hey @afonsonf, when I tried creating a Codespace, it ended up being in recovery mode without apt, npm, and other essential components. I'm completely lost here. Could you please take a look at it?

It fails to install the java jre 11, because its no longer in the default package repos distributed in the base image, I'll fix it
