Release 2024.05.22

Added support for user defined fields on Stripe Invoices.
Added optional support for writing null values when model syncing to Snowflake.
Enabled additional features for Attio model syncs:
- Non-unique fields in Attio may be used in the identity mapping.
- Array fields used as the model identity value will look for each element in Attio; this allows the use of an array of email addresses in the identity mapping for People, for example.

Snowflake replace-mode syncs could report an inaccurate error count under some circumstances.
Record creation timestamps were not populated for Snowflake replace-mode model syncs.
Apollo enrichment was applied to the wrong record under rare circumstances.
Temporary stages used by Snowflake model syncs in append or replace mode were not consistently removed after syncing.
Databricks connections did not correctly verify S3 access during healthchecks.
Improvemets to SSH tunnel shutdown when used with Postgresql replication.
