It's not. A bill of attainder declares a specific person guilty for past actions and punishing them - thereby denying them the right to a judicial trial.
While this bill does refer to a specific organization, it doesn't punish them for past actions, but rather constrains US companies in the future. That is perfectly ok as shown in cases like Huawei v. United States or Kaspersky Lab, Inc. v. DHS. Like Kaspersky, it's "prophylactic, not punitive."
