Dead link to reporting form for inappropriate behavior at Center events

[SethTisue]

as seen at e.g. https://github.com/scala/scala.epfl.ch/actions/runs/11857417247/job/33045742148

* At ./_site/events.html:464:

  External link https://docs.google.com/forms/d/e/1FAIpQLSccVqGPhCd-a3a-AvCPFAqzg0mSPPTE-vNU3yXCNb-5qFunvA/viewform failed (status code 410)

the context is https://scala.epfl.ch/events

Please note that the Scala Center ensures welcoming and safe spaces on all our events. Both the EPFL and Scala Code of Conducts apply. We encourage you to report inappropriate behavior either through EPFL channels or directly to us. Depending on what seems most comfortable to you, use one of the following channels: a) send an email to scala.center@epfl.ch (the Scala Center staff receives it), b) send an email to one member of our staff, or c) anonymously fill in this form. We take reports seriously and react as quickly as possible to find appropriate solutions. Our entire staff is receiving continuous training in how to handle basic reported cases. For more complex ones, we may either reach out to appropriate EPFL channels or a mediation company that supports us. All cases are treated respectfully and with full confidentiality.

@darjutak what should we do here?

to fix CI, I replaced the link with a link to this ticket: 82e3518

at the moment we don't have any events coming up, but we should sort this out before Scala Days 2025 if not before
