Subject: [PATCH] chore: switch stdenv.is* to stdenv.hostPlatform.is*

Update pkgs.stdenv.is* as it has been deprecated from nixpkgs:
https://github.com/NixOS/nixpkgs/commit/4bb4cff

```
   stdenv: deprecate is* aliases in favor of hostPlatform.is*
   These shorthands hide the platform distinction and are unfit for
   cross-compilation. Wrap them in `lib.warn` so each access prints a
   deprecation notice, and gate them on `config.allowAliases` so they
   can be removed entirely.
```

The commit introduces a deprecation notice:

```nix
   lib.warn "stdenv.${name} is deprecated, use stdenv.hostPlatform.${name} instead" value
```
