Subject: [PATCH] cargo-lambda: zig_0_13 -> zig

cargo-lambda, as far as we can tell, only uses zig to call into
cargo-zigbuild. cargo-zigbuild supports the latest versions of zig, and
the main `cargo-zigbuild` derivation seems to have had a fine time with
an unpinned zig. since we aim to drop zig 0.13 soon as it depends on the
long-eol llvm 18, we unpin this to work towards that.

we do not use aws lambda, and thus cannot entirely test this, but
initing a simple test project with `cargo lambda new` and building a
project with `cargo lambda build` (which should default to using
`cargo-zigbuild` interally) appears to work fine.
