Zig Version

0.16.0

Steps to Reproduce and Observed Behavior

Run this (note it will clear your zig cache):

cd "$(mktemp -d)"
zig init
rm -rf ~/.cache/zig
zig fetch "https://github.com/dearimgui/dear_bindings/releases/download/DearBindings_v0.19_ImGui_v1.92.7/DearBindings_v0.19_ImGui_v1.92.7.zip"

fails with error: failed to create temporary zip file: FileNotFound.

Expected Behavior

Fetch to succeed.

Notes

As far as I can tell, the issue was introduced in #31121. Given that this worked in 0.15 and thus regresses an existing feature, I would appreciate if it was fixed in a 0.16 patch release.
