fix: zip size not being calculated correctly

somehow adding a zip with entries using the `adm-zip` constructor differs from adding the zip entries using the `addFile` method

If I use the constructor to create the zip, and then send that zip to the server I was receiving the error `invalid entry size (expected 2187395080 but got 158 bytes)`
