fix(interaction): add pointer when clicking the speakers cards for more info

[khairalanam]

Description:
I like the addition of "info" icons for the speakers' cards for information but it would be better if a desktop user could use the mouse to click anywhere inside the card to flip to see the information.

Solution:
First, set the cursor to a pointer in CSS when inside the card.
Second, when clicked, assign the event to the same event as when clicking the "info" icon
