popover_menu: Add docs to the `trigger_with_tooltip` method (#25158)

Felt like this was relevant particularly as we're living with both
`trigger` and `trigger_with_tooltip`. At some point, I believe there
should be only one (`trigger_with_tooltip`) and that should be then
renamed to just `trigger` back again! We're supporting both for now just
for ease of migration/avoiding big changes.
