I'm not sure about the indentation rules for .mojom, but in general lines should
be max. 80 characters long.
(Also on line 44.)

Done. Keep lines length within 80 characters and mimic indentation rules from
other .mojom files.

+  // or null with a CredentialManagerError if failed.
+  Get(bool zero_click_only,
+      bool include_passwords,
+      array<string> federations) => (CredentialManagerError error, CredentialInfo? credential);
+};
