Improve documentations : Describe running with minikube

[grzesuav]

hi,

I wanted to evaluate coroot.
I was able to setup prometheus + clickhouse + coroot, what I am dealing right now is to install node-agent, which seems to crash:

additional instructions would be nice, I expect issue is caused as control-plane and worker nodes are run in docker.

However still kind installation instruction would be nice

Hello!

Your variables are not defined
#########
tracesEndpoint
logsEndpoint
#########

check yours values.yml

in example node-agent:
###########
node-agent:
enabled: true
tracesEndpoint: "http://coroot-opentelemetry-collector:4318/v1/traces"
logsEndpoint: "http://coroot-opentelemetry-collector:4318/v1/logs"
###########

[grzesuav]

@apetruhin thanks, it explains it - would be helpful to see it in documentation, along with pointing to minikube with VM driver

[grzesuav]

What I mean is - currently is mentioning

Limitations:
Coroot doesn't support Docker-in-Docker environments such as MiniKube due to [eBPF limitations](https://github.com/coroot/coroot/issues/10#issuecomment-1345201225)

which is clearly not true - I just setup minikube to run it with qemu
