Document dynamic cockpit link resolution

[barmac]

What should we do?

To make #4261 discoverable, we need to document it.

There is no dedicated Camunda 7 deployment page on docs.camunda.io. The existing deployment documentation page is about Camunda 8.

This needs to be implemented in https://github.com/camunda/camunda-docs repo.

Why should we do it?

We want our features to be usable, and lacking documentation hinders it.
