Migrate more events to telemetry::event! macro (#24102)

I believe this takes care of the remaining events running through the
old flow that requires transformation at the collab server level. I
think all events are now going through `telemetry::event!()`.

For anyone curious where the new telemetry names are coming from, you
can check the `for_snowflake` function within
`crates/collab/src/api/events.rs`, to see how collab is currently
transforming the events going through the old flow.
