get_crate_manifest_path

A function that returns the path to the manifest file for a given crate name.
/// Returns the manifest file path of the specified crate.
///
/// Uses the `cargo metadata` command to obtain metadata about the current project's dependencies,
/// and returns the path to the manifest file (`Cargo.toml`) of the crate that matches the specified crate name.
///
/// # Arguments
///
/// * `target_crate_name` - The crate name to search for (e.g., "serde")
///
/// # Returns
///
/// A `String` representing the path to the specified crate's manifest file.
/// This function will panic if the crate cannot be found.
///
/// # Example
///
/// ```
/// use get_crate_manifest_path::get_crate_manifest_path;
///
/// let manifest_path = get_crate_manifest_path("serde");
///
/// println!("serde crate manifest path: {}", manifest_path);
/// ```
///
/// # Note
///
/// This function assumes that the cargo command is installed on the system.
/// Also, depending on the environment, it may affect performance.
