Enterprise-ng: ToolbarFlex: Correct the SohoToolbarFlexEvent.item type definition

[ayoayco]

Is your feature request related to a problem? Please describe.
It seems the soho-toolbar-flex typescript definition is not yet updated to include the type for the item property (SohoToolbarFlexSelectedEvent.item). It appears from using Chrome dev tools that it should be ToolbarFlexItem but from the typescript definitions in the library for our code we are getting the type HTMLButtonElement | HTMLAnchorElement | HTMLInputElement

Describe the solution you'd like
Update the typescript definition for SohoToolbarFlexSelectedEvent.item property to be the correct one.

Describe alternatives you've considered
I tried typesetting but this creates a bit more code changes on our app

Additional context
Please consider the code below:

    getSelectedData(event: SohoToolbarFlexSelectedEvent) {
        let dataset;
        if (event.item.type === 'actionbutton' || event.item.type === 'menubutton') {
            // produces linting error here since item property's type is not correct
            dataset = event.item.selectedAnchor[0].dataset;
        } else {
            // produces linting error here since item property's type is not correct
            dataset = event.item.element.dataset;

        }
        return dataset;
    }
