_index.md: re-order the projects and minor word tweaks

1. rename containerd spin shim -> containerd shim spin for consistency
2. Move the Spin operator to the top of the projects page
3. Rename 'Overview' to 'SpinKube Projects'
4. Remove over-explaination of projects

+**Spin Operator** The [Spin Operator](https://github.com/spinkube/spin-operator/) enables deploying
+Spin applications to Kubernetes. The foundation of this project is built using the
+[kubebuilder](https://github.com/kubernetes-sigs/kubebuilder) framework. Spin Operator defines Spin
+App Custom Resource Definitions (CRDs). Spin Operator watches SpinApp Custom Resources e.g. Spin app
+image, replicas, schedulers and other user-defined values and realizes the desired state in the
+Kubernetes cluster. Spin Operator introduces a host of functionality such as resource-based scaling
+event-driven scaling and much more.
 
 **Containerd Shim Spin** The [Containerd Shim Spin
 repository](https://github.com/spinkube/containerd-shim-spin) provides shim implementations for

+Kubernetes](https://github.com/spinkube/spin-plugin-kube) is a Spin Plugin, designed to enhance Kubernetes by
 enabling the execution of Wasm modules directly within a Kubernetes cluster. This plugin works by
 integrating with containerd shims, allowing Kubernetes to manage and run Wasm workloads in a way
 similar to traditional container workloads.

 **Spin Trigger MQTT** [Spin Trigger MQTT](https://github.com/spinkube/spin-trigger-mqtt/) is an MQTT
 trigger designed specifically for Spin. It enables seamless integration between Spin and MQTT-based
 systems, allowing you to automate workflows and trigger actions based on MQTT messages.
