GridActiveItemChangedEvent is mentioned in the documentation but can't be imported

[Alos]

Description

While using vaadin-grid web component 5.7.7 I'm unable to import GridActiveItemChangedEvent as shown here:
https://vaadin.com/docs/latest/ds/components/grid/#single-selection-mode. VSCode is unable to import this from:

import type {GridActiveItemChangedEvent} from '@vaadin/vaadin-grid';

Expected outcome

GridActiveItemChangedEvent is included in '@vaadin/vaadin-grid` and I can import the event to my TS app.

Steps to reproduce

Clear steps describing how to reproduce the issue.

1. Add vaadin-grid 5.7.7 to a project
2. Try to import GridActiveItemChangedEvent

Thanks for the issue. Please note the link points to the latest version which is currently 22.0 and this feature is supported there. The vaadin-grid 5.x is an older version and it does not provide type definitions for custom events.
