fix: use drasi apply instead of kubectl apply for Drasi resources (#85)

[sahajdeepsingh651]

Problem

The Dapr + Drasi tutorial instructs users to apply Drasi resources using kubectl apply.
This fails because Drasi resources (Source, ContinuousQuery, Reaction) are not Kubernetes CRDs and must be applied using the drasi apply command.

This issue appears in multiple files:

• tutorial/dapr/README.md
• tutorial/dapr/scripts/setup-tutorial.sh
• tutorial/dapr/scripts/setup-tutorial.ps1
• .devcontainer/dapr/post-create.sh

Solution

Updated all instructions to use drasi apply -f <dir>/* instead of kubectl apply -f <dir>/.

Verification

After applying the changes:

1. drasi apply -f drasi/sources/* works without errors
2. drasi apply -f drasi/queries/* works without errors
3. drasi apply -f drasi/reactions/* works without errors

This ensures the tutorial works as expected and Drasi-powered services run correctly.

Fixes #85
