https://github.com/odoo/odoo/pull/110188 introduced a change in the TagsList
component, making the className prop be used in the parent tag rather than the
image tag. This change makes sense as most times you want to add classes to the
root element in the component. However, in calendar, we used className to style
the image tag, to allow showing the calendar attendee status for an event. This
commit introduces the imageClass property that should be passed in the tags
prop. Therefore, tags list will now have both className and imageClass, making
it possible to style both tags.
