Change is due to manageTrailingCommas now being a trailingCommaManagementStrategy enum: https://github.com/facebook/ktfmt/releases/tag/v0.57

FormattingOptions.manageTrailingCommas was replaced with FormattingOptions.trailingCommaManagementStrategy, which also added new TrailingCommaManagementStrategy.ONLY_ADD strategy (facebook/ktfmt#461, facebook/ktfmt#512, facebook/ktfmt#514)
