[Internal]: Clarify ECK license doc

[kunisen]

Description

Current ECK license doc is causing confusion in terms of updating.
It's not very clearly mentioning the command example to update license.
The customer has to rely on our KB to do it.

We see this pop up from time to time (myself has experience this twice, we also have KBs regarding this topic and was referenced multiple times.)
