Loki schema config change uses a date in the past

The latest Loki upgrade (v3) has a new schema change. In the Big Bang implementation the date to start using this schema was set to April 1, 2024. The docs for Loki say that from dates on an upgrade should always be set to the future - ref https://grafana.com/docs/loki/latest/operations/storage/schema/#changing-the-schema

This seems pretty critical as it makes data in between the from date and the actual upgrade date unreadable:

If you then try to query data that was written between 00:00:00 and 01:00:00 UTC, Loki will use the new schema and the data will be unreadable, because it was created with the previous schema.

I believe at minimum this should be called out in release notes, but likely also should change the default date.
