Use rust-analyzer from tool chain in devShell — heartwood

The devShell now uses rust-analyzer from the tool chain. Previously, using the nixpkgs rust-analyzer (from an older rust version) led to inaccurate results.

         commonArgs = mkCommonArgs craneLib;
       };
       rustupDevShell = rec {
         toolchain = rustup.toolchain.override (prev: {
           extensions = prev.extensions ++ ["rust-analyzer"];
         });
         craneLib = (crane.mkLib pkgs).overrideToolchain toolchain;
         commonArgs = mkCommonArgs craneLib;
       };
       srcFilters = path: type:
         builtins.any (suffix: lib.hasSuffix suffix path) [
           ".sql" # schemas

           };
         };
       devShells.default = rustup.craneLib.devShell {
       devShells.default = rustupDevShell.craneLib.devShell {
         inherit (self.checks.${system}.pre-commit-check) shellHook;
         buildInputs = self.checks.${system}.pre-commit-check.enabledPackages;
