Dev Container will not load after migration to tutorials

[paulyuk]

The quickstarts have a Dev Container available with all runtimes and dapr CLI.

When dapr/quickstarts loads it no longer finds the dev container definition, and instead loads the generic one. As a result there is no Dapr CLI or other things we need.

The Root cause is .devcontainer folder needs to be at the root level, but it got moved/refactored under ./tutorials.

Steps to Reproduce the Problem

Create a dev container from Code button in dapr/quickstarts repo. You will need the required Github teams or equivalent SKU.
