pub const ENTITY_UPDATE: &str = "\
Change the fields of a project, portfolio or goal.
```
ytcli project update 655… -s \"Storage rework, phase two\"
ytcli portfolio update 655… --lead ilubenets --end 2026-12-31
```
Two requests: the entity is read first for its version, so a change somebody
else made in between is refused by Tracker rather than overwritten. Passing no
field is refused before anything is sent.";
