We previously determined if a build variant was an enterprise module by checking for the presence of 'enterprise' in the build variant's modules parameter. Since the removal of the modules:enterprise, we need to have a new method for this determination.

Note: This occurs both in 10gen/mongo and mongo-task-generator (https://github.com/mongodb/mongo-task-generator/blob/9812bcef27854ca4d530e5b508513ea01b47ad54/src/evergreen/evg_config_utils.rs#L719-L725 ).
