No tooltip when hovering over calendar icon in event list

[LeandraH]

Describe the Bug

When I go to the list of events, I have calendar icons on the right of each event. When hovering over that, I used to get a tooltip telling me what the icon means. That is currently not happening.

Steps to Reproduce

1. Go to 'https://integreat.app/augsburg/de/events'
2. Hover over the first calendar icon
3. See no tooltip

Expected Behavior

A tooltip pops up when I hover over the icon.

Actual Behavior

No tooltip pops up.

@LeandraH is this fixed in #2847 as a side-effect of replacing our tooltip component with react-tooltip?
