Fixes #36684
Add documentation about multiple transaction managers sharing same resource
This PR adds documentation to clarify the behavior when multiple DataSourceTransactionManager instances are configured with the same underlying DataSource.
Changes:
The documentation clarifies that Spring's transaction synchronization is based on the resource (DataSource) itself, not on the transaction manager instance, allowing transactions from different managers to coordinate automatically.
