Update devcontainer image version typescript-node:20

[stamat]

Summary

Node 18 needed for Storybook 8 to be run. Current node version is 16, therefore the image version for the container is upped to 18. I just wanted to be able to run npm run start right away after Codespaces loads.

List of notable changes:

• updated dev container image version from typescript-node:16 to typescript-node:20

What should reviewers focus on?

• Verify that the node -v is indeed 20

Steps to test:

1. Create a new codespace
2. Run node -v
3. Should say v20.x.x

P.S. Tested it myself works.
