txn_participant_adds_additional_participants_with_aborts and txn_participant_adds_additional_participants both assume the only transactions executed during the test are from the transactions created during the test.

An internal transaction can take place, for example refreshing the FCV is run in an internal transaction.

This changes the serverStatus transactions metrics that are expected in the test.

To fix we can change the equality to check to a greater than or equal to check to account for transaction running in the background.
