Notion API update 2025-09-03

[GTFalcao]

Notion is introducing multi-source databases, and we need to update our components: https://developers.notion.com/docs/upgrade-guide-2025-09-03

What's Changing
The new API version introduces clearer separation between databases (containers for organizing your data) and data > sources (the actual tables of data within a database). This means:

• Current /v1/databases endpoints will be renamed to /v1/data_sources for data operations
• New /v1/databases endpoints will manage the container itself, managing a list of child data_sources
• The database_id parameter in APIs like Create Page becomes data_source_id
