chore: update dependencies

[reneleonhardt]

Chores

• Update devcontainer dependencies, Docker images and github-actions
• Let dependabot update devcontainers, docker, github-actions, gomod, npm, pip and uv

[reneleonhardt]

Notes

• Most make commands in README don't exist
• npm dependencies are too old, everything is breaking now
