Feature Request: Don't send dropped session recordings to Sentry

Feature request

Is your feature request related to a problem?

If the user has a minimum duration for recordings, and the session doesn't meet that, it'll be dropped, but we'll still send the link to Sentry. This is confusing.

Describe the solution you'd like

Ideally, in such cases we'd send just the session ID and say there's no recording.

Describe alternatives you've considered

Use the session ID included in the replay link to filter events from that session: https://us.posthog.com/project/PROJECT_ID/replay/SESSION_ID (looks like this: 01983cd2-d486-757f-aaeb-80185ffcce8e)

Start in the session_replay area and trace where recordings that miss the minimum duration are turned into Sentry links. Use the session ID and dropped-recording behavior described in the issue as the acceptance criteria: Sentry should receive the session ID without a recording link, and the relevant behavior should be covered by tests.
