`haveI` has been replaced by `have`

[fweth]

Describe the bug
https://lean-lang.org/doc/reference/latest/Tactic-Proofs/The-Tactic-Language/#have

In what way is the content incorrect?

Seems like haveI has been accidentally replaced by another copy of have

Please provide a self-contained Lean example that demonstrates the incorrectness of the statement.
