Describe the bug

If you set environment variable through cargo config.toml file, like below, cargo tauri dev doesn't add it to the target app.

.cargo/config.toml

[env]
FOO = "bar"

Reproduction

preprare barebone tauri-app

cargo install create-tauri-app --locked
cargo create-tauri-app

edit tauri-app/src-tauri/src/main.rs


#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]

[tauri::command]

fn greet(name: &str) -> String { format!("Hello, {}! You've been greeted from Rust!", name) }

fn main() {

match std::env::var("FOO") {
    Ok(v) => println!("FOO={v}"),
    Err(e) => println!("Error: {:?}",e),
}

tauri::Builder::default()
    .invoke_handler(tauri::generate_handler![greet])
    .run(tauri::generate_context!())
    .expect("error while running tauri application");

}


3. edit **.cargo/config.toml**
```toml
[env]
FOO = "bar"

run cargo tauri dev

/r/tauri-app> cargo tauri dev Info Watching tauri-app/src-tauri for changes... Compiling tauri-app v0.0.0 (tauri-app/src-tauri) Finished dev [unoptimized + debuginfo] target(s) in 2.55s Error: NotPresent

Expected behavior

Running command cargo tauri dev should print below.

/r/tauri-app> cargo tauri dev Info Watching tauri-app/src-tauri for changes... Compiling tauri-app v0.0.0 (tauri-app/src-tauri) Finished dev [unoptimized + debuginfo] target(s) in 2.55s FOO=bar

Additional context

If we run tauri-app by running command cd src-tauri; cargo run, the app correctly prints the environment variable set by .cargo/config.toml.
