20240518: Nixpkgs 23.11 and unstable support (#87)

We add support for building nixpkgs 23.11 and unstable. However, there are some caveats, which is summarized in the table below:


|                  | 23.05  | 23.11  | unstable |
| -------------    | ------ | ------ | -------- |
| darwin x86_64    |    ⍻    |   ❌    |   ❌    |
| linux  x86_64    |   ✅︎    |   ✅︎    |   ✅︎    |
| darwin aarch64   |   ⍻    |   ⍻    |   ✅︎    |

✅︎: builds with no issue
❌: does not build
 ⍻: builds but binaries have extra dynamic lib dependency to Nix store
