Adding devcontainer

[xN4P4LM]

This PR adds a devcontainer for easier local development, to use either use vscode devcontainers or a github codespace

The way I understand the devcontainers dependabot is it will only update the hash of an tag if it is newer. Since we do not specify a hash in the devcontainer.json, it wont update anything

For me the dev container does not work. When I run npm run preview it runs on a port. Dev containers correctly notices that the port is being listened on and it says that it has opened the port from the container, but when I go to the localhost:<whatever_port> it does not load the webpage. I even tried clicking on the link VSCode suggests I go to to view the site (same one I previously went to) and it still did not load. Not sure if it is a problem with the dev container or our build process.

This does not seem to fix the issue for me

plz add dependabot back. They do publish multiple containers per tag when nodejs updates
