services::Fs shouldn't trim path names with spaces when listing

Nice catch! OpenDAL has some limitations on path to make sure all services behave like the same:

opendal/core/src/raw/path.rs

Lines 85 to 96 in 918f9c0

	/// Make sure all operation are constructed by normalized path:
	///
	/// - Path endswith `/` means it's a dir path.
	/// - Otherwise, it's a file path.
	///
	/// # Normalize Rules
	///
	/// - All whitespace will be trimmed: ` abc/def ` => `abc/def`
	/// - All leading / will be trimmed: `///abc` => `abc`
	/// - Internal // will be replaced by /: `abc///def` => `abc/def`
	/// - Empty path will be `/`: `` => `/`
	pub fn normalize_path(path: &str) -> String {

Maybe we should raise an error for invalid path instead.
