Migration guide was covered in #1069

@NissesSenap I've just marked these items as completed:

• v4 -> v5 migration guide;
• jsonnet;
• custom folder examples.

The only item that is left now is operator metrics. Do you, by chance, remember what exactly we planned to describe in docs? - The link that is added to the item points at the instruction on how to disable RBAC proxy in v4, and the proxy was removed in #1030, which means that a similar section is not needed. Unless we planned to add something else, we can probably mark it as completed as well. WDYT?

Agreed, i will close the issue as done
