chore: do not render consume update in scaladoc

[hamzaremmal]

In #23755, a consume method now implies an update method.
This PR changes the rendering in scaladoc to avoid printing consume update def and rather print consume def.
Note that at the moment, in #23755, writing consume update def or consume def has the same effect.
An error or a warning might be added in the future to highlight that update in consume update def is a redundant modifier.
