Allows overriding transaction behavior in migrateUp

Adds the ability to override the `disableTransactions` setting when calling the `migrateUp` method, providing more granular control over transaction usage during migrations.

This allows users to selectively enable or disable transactions for specific migration runs, regardless of the default setting on the `Migrator` instance.
