Publish an RSS feed for Events

[sabine]

Similar to the OCaml Changelog, Events should be provided as a RSS feed (so that we can connect them with social media accounts on Twitter, LinkedIn, and Mastodon).

Hints:

• Look at the implementation of RSS feeds for the OCaml Changelog (https://github.com/ocaml/ocaml.org/blob/main/tool/ood-gen/lib/changelog.ml) as inspiration for how to do this for Events (https://github.com/ocaml/ocaml.org/blob/main/tool/ood-gen/lib/event.ml).
• The create_feed function for Events needs to be registered as a sub-command of ood-gen here: https://github.com/ocaml/ocaml.org/blob/main/tool/ood-gen/bin/gen.ml
• You need to add a dune rule at https://github.com/ocaml/ocaml.org/blob/main/dune that runs the ood-gen tool to create the .xml file.
• Update the template at events.eml to add a link to the RSS feed.

As a reminder, ocaml.org currently publishes two feeds:

• https://ocaml.org/feed.xml
• https://ocaml.org/blog/opam/feed.xml

This is about publishing a third one.
