Add a calendar name to the ICS feed. (#1912)

Add a calendar name to the ICS, to give Giggity and other clients a conference name.
Inspired from https://www.paris-web.fr/2025/conferences-paris-web-2025.ics
We could also add a `X-WR-CALDESC`description, but the `X-WR-CALNAME` seems to be the most important one.
