Devcontainer

[ludeeus]

Breaking change

Proposed change

Adds:

• devcontainer (That includes the runtime needed for developing the frontend and running core)
• New tasks:
  • "Develop Supervisor panel" to develop the Supervisor panel
  • "Run HA Core in devcontainer" to start HA Core
  • "Run HA Core for Supervisor in devcontainer" to start HA with requested input values for a remote proxy add-on

With both the new run tasks a base config directory will be created.

This is compatible with GitHub's codespaces, but the time from start to onboarding takes ~15min, so stick with local use 🙈
