Add Kubernetes configuration for Firecrawl deployment

Added new files for setting up Firecrawl on a Kubernetes Cluster. The files include Kubernetes manifests for deploying API, worker, playwright service, and Redis with associated ConfigMap and Secret associated resources. Also, updated the self-host documentation to include instructions for Kubernetes deployment.

+# Install Firecrawl on a Kubernetes Cluster (Simple Version)
+# Before installing
+1. Set [secret.yaml](secret.yaml) and [configmap.yaml](configmap.yaml) and do not check in secrets
+2. Build Docker images, and host it in your Docker Registry (replace the target registry with your own)
+   1. API (which is also used as a worker image)
+      1. ```bash
+         docker build -t ghcr.io/winkk-dev/firecrawl-playwright:latest ../../apps/api
+         docker push ghcr.io/winkk-dev/firecrawl-playwright:latest
+         ```
+   2. Playwright 
+      1. ```bash
+            docker build -t ghcr.io/winkk-dev/firecrawl:latest ../../apps/playwright-service
+            docker push ghcr.io/winkk-dev/firecrawl:latest
+         ```
+3. Replace the image in [worker.yaml](worker.yaml), [api.yaml](api.yaml) and [playwright-service.yaml](playwright-service.yaml)
+4. 
+
+## Install
+```bash
+kubectl apply -f configmap.yaml
+kubectl apply -f secret.yaml
+kubectl apply -f playwright-service.yaml
+kubectl apply -f api.yaml
+kubectl apply -f worker.yaml
+kubectl apply -f redis.yaml
+```

+
+# Port Forwarding for Testing
+```bash
+kubectl port-forward svc/api 3002:3002 -n dev
+```
+
+# Delete Firecrawl on Environment
+```bash
+kubectl delete -f configmap.yaml
+kubectl delete -f secret.yaml
+kubectl delete -f playwright-service.yaml
+kubectl delete -f api.yaml
+kubectl delete -f worker.yaml
+kubectl delete -f redis.yaml
