update of macOS client always fails

Describe the bug macOS client is unable to update itself

To Reproduce

I run my client on macOS like this:

(base) [dkoski@dkoski-14 VPin-Studio-Client-macosx_aarch64 ]$ sh VPin-Studio-macosx_aarch64.sh

I have updated client & server many times: the server updated via the clicked button in the UI and I always downloaded the new client from GitHub. This time I noticed in the logs that it looks like it was supposed to update the client as well, but I found that it actually did not:

(base) [dkoski@dkoski-14 VPin-Studio-Client-macosx_aarch64 ]$ sh update-client.sh 
unzip:  cannot find or open vpin-studio-ui-jar.zip, vpin-studio-ui-jar.zip.zip or vpin-studio-ui-jar.zip.ZIP.
rm: vpin-studio-ui-jar.zip: No such file or directory
update-client.sh: line 5: ./VPin-Studio.sh: No such file or directory

Sure enough, there is no vpin-studio-ui-jar.zip anywhere that I can see (despite the logs indicating that it was downloaded to /Users/dkoski/pinball/VPin-Studio-Client-macosx_aarch64/./vpin-studio-ui-jar.zip, which is the current directory where the client runs).

I manually copy over the contents of the zip that I download and that does work fine.

Expected behavior

Expected:

the download of the new client would put a vpin-studio-ui-jar.zip in the local directory
the update script would work

Screenshots

No, but see logs above.
