Madhu Rajanna c2cbb25489 doc: remove contacts from Readme
The twitter and google forum is
not maintained and doesnt have
any updates, This is the good
chance to remove the same from
the cephcsi readme as well.

This repo contains the Ceph
[Container Storage Interface (CSI)](https://github.com/container-storage-interface/)
driver for RBD, CephFS and Kubernetes sidecar deployment YAMLs to support CSI
functionality: provisioner, attacher, resizer, driver-registrar and snapshotter.
## Overview
Ceph CSI plugins implement an interface between a CSI-enabled Container Orchestrator
(CO) and Ceph clusters. They enable dynamically provisioning Ceph volumes and
attaching them to workloads.
Independent CSI plugins are provided to support RBD and CephFS backed volumes,
- For details about configuration and deployment of RBD plugin, please refer
[rbd doc](https://github.com/ceph/ceph-csi/blob/devel/docs/deploy-rbd.md) and
for CephFS plugin configuration and deployment please
refer [cephFS doc](https://github.com/ceph/ceph-csi/blob/devel/docs/deploy-cephfs.md).
- For example usage of the RBD and CephFS CSI plugins, see examples in `examples/`.
- Stale resource cleanup, please refer [cleanup doc](docs/resource-cleanup.md).
NOTE:
- Ceph CSI **`Arm64`** support is experimental.
## Project status
Status: **GA**
## Known to work CO platforms
Ceph CSI drivers are currently developed and tested **exclusively** in Kubernetes
environments.
| Ceph CSI Version | Container Orchestrator Name | Version Tested |
| -----------------| --------------------------- | -------------------|
| v3.12.0 | Kubernetes | v1.29, v1.30, v1.31|
| v3.11.0 | Kubernetes | v1.26, v1.27, v1.28, v1.29|
There is work in progress to make this CO-independent and thus
support other orchestration environments (Nomad, Mesos..etc).
NOTE:
The supported window of Ceph CSI versions is "N.(x-1)":
(N (Latest major release) . (x (Latest minor release) - 1)).
For example, if the Ceph CSI latest major version is `3.9.0` today, support is
provided for the versions above `3.8.0`. If users are running an unsupported
Ceph CSI version, they will be asked to upgrade when requesting support.
## Support Matrix
### Ceph-CSI features and available versions
Please refer [rbd nbd mounter](./docs/rbd-nbd.md#support-matrix)
