feat: add Node.js to devcontainer and reduce size

[falsepopsky]

• feat: added Node.js
• chore: to improve readability and prevent conflicts with potentially added options, the configuration was moved from the devcontainer.json file to the .vscode folder.
• fix: the latest configuration contains duplicated code (repo) in folders:
  • workspaces
  • workspace

with the new update we just work in workspaces

for some reason the commnds in the dockerfile doesn't work with the new config, probably because the context path, so for now i just moved the installation in postCreateCommand

i need to check that labeler workflow the config it's okay but doesn't work on forked repos in the new version (interesting !), also:
