The `generate-windows-launcher` job fails intermittently on `cs` download timeout

Describe the bug
The generate-windows-launcher job got extremely flaky, seemingly failing very often on the cs download.
We should investigate and try to fix it, as it otherwise forces us to restart jobs to no end.

Example failing build:

• https://github.com/VirtusLab/scala-cli/actions/runs/9203658473/job/25315612689?pr=2920#step:5:250

Example output:

download error: Caught java.net.ConnectException (Connection timed out: connect) while downloading https://download.libsodium.org/libsodium/releases/libsodium-1.0.18-stable-msvc.zip
1 targets failed

To Reproduce
Just run any CI job on main, the generate-windows-launcher job will fail ~4 times out of 5.

Expected behaviour
The generate-windows-launcher job should be passing consistently.

Potential solutions
We could try increasing the timeout or retrying the download.
