feat: Migration #122 set useTransactionSimulations to true

[digiwand]

Description

This migration sets useTransactionSimulations to true. Some users may have explicitly turned off the experimental setting, which this migration will reset to true. This is intentional as we also plan to remove the setting in an upcoming release.
