docs: version bump and general updates

[andy108369]

After having tested them on the Hurricane provider, it's time to bump the docs.

• [x] kubespray 2.21.0 => 2.23.0
• [x] nginx-ingress controller 4.7.1 => 4.7.2
• [x] metallb 0.13.7 => 0.13.11
• [x] rook/ceph v1.12.3 => v1.12.4

---

Additionally

• [x] I think it is worth extending this doc https://docs.akash.network/akash-nodes/akash-node-via-helm-charts/node-verifications with the following verification methods:

1) From the K8s control-plane node directly

export AKASH_NODE="http://$(kubectl -n akash-services get ep akash-node-1 -o jsonpath='{.subsets[0].addresses[0].ip}'):26657"

curl -s "$AKASH_NODE/status" | jq -r .

2) From a remote address (outside the K8s network)

You can use kubectl port-forward for forwarding the akash node (RPC) port 26657/tcp to your local station.

1. Forward 26657 to 127.0.0.1:26657

   $ kubectl -n akash-services port-forward service/akash-node-1 26657:26657
   Forwarding from 127.0.0.1:26657 -> 26657
   Forwarding from [::1]:26657 -> 26657

2. Put the kubectl port-forward process into background

Press Ctrl+Z and type bg + Enter as follows:

^Z
[1]+  Stopped                 kubectl -n akash-services port-forward service/akash-node-1 26657:26657
$ bg
[1]+ kubectl -n akash-services port-forward service/akash-node-1 26657:26657 &

3. After that you can access the RPC as if it were running locally

$ curl -s http://127.0.0.1:26657/status | jq -r .

4. Stop kubectl port-forward after you are done

$ jobs
[1]+  Running                 kubectl -n akash-services port-forward service/akash-node-1 26657:26657 &
$ kill %1
$ jobs
[1]+  Terminated              kubectl -n akash-services port-forward service/akash-node-1 26657:26657

• [x] Please update the example https://docs.akash.network/providers/build-a-cloud-provider/akash-provider-bid-pricing/example-command-use with ibc-gpu-3-services-1-gpu-each-different.jq -- from https://github.com/akash-network/helm-charts/pull/226

As well as adding the example with specifying PRICE_TARGET_CPU=1.60 PRICE_TARGET_MEMORY=0.80 ... on the CLI (also in that PR comment)
