zig: Fix template build

[mrBen]

I'm not sure when or why these changes occurred in Zig, but with this fix I can compile the template on the latest version of Zig.

I don't know how to link it, but it fixes #685.

This was a fairly recent change in Zig, hopefully there will be a 0.12.0 release soon:ish :)

The changes in https://github.com/ziglang/zig/pull/18160 likely broke a fair amount of existing code.

[!NOTE] I have my own little project that I try to keep up to date for coding WASM-4 carts in Zig ⚡ https://github.com/peterhellberg/w4-init

Thanks, it's hard to keep on top of all these breaking Zig changes 😬
