Move epic ownership expectation to epic ownership description.
From https://handbook.opencraft.com/en/latest/epic_management/#tips-and-tricks:
Also keep in mind that if you do the discovery for a future epic, you will be expected to take on the epic owner role for that epic later on (if/when the client gives us the go-ahead for starting the work).
I feel like this should be in the parent section as this is not a tip, but a requirement in most cases.
