feat(feedback): add feedback as new event type

[JoshFerge]

• Adds the feedback event type. See https://github.com/getsentry/team-replay/issues/222
• We'll be leveraging the issue platform to create issues, and these feedbacks will flow in from relay on the events topic and be picked up in the ingest consumer and have issues created via issue platform, which is why we need the event type on both.

versions in use:

The following repositories use one of the schemas you are editing. It is recommended to roll out schema changes in small PRs, meaning that if those used versions lag behind the latest, it is probably best to update those services before rolling out your change.

• getsentry/sentry: pip:sentry-kafka-schemas==0.1.32
• getsentry/snuba: pip:sentry-kafka-schemas==0.1.32
• getsentry/snuba: rust:sentry-kafka-schemas==0.1.32

latest version: 0.1.32

There were changes to the JSON schema file, but we couldn't categorize any of
them. Therefore we don't know whether this change is safe to make.

This might be a gap in linting. Want to take a look at
https://github.com/getsentry/json-schema-diff/ and figure it out?

should be fine to roll out as this change is additive.

Just out of curiosity, how come we're changing events too? Is it not just an issue platform change?

feedbacks are going to be a new event type in addition to new issue type.
