`db.connect` panics when used in a single threaded environment

[avinassh]

Consider this code (introduced via this PR: #2029)

libsql/libsql/src/database.rs

Lines 685 to 695 in 10f5dd8

	let _ = tokio::task::block_in_place(move || {
	let rt = tokio::runtime::Builder::new_current_thread()
	.enable_all()
	.build()
	.unwrap();
	rt.block_on(async {
	// we will ignore if any errors occurred during the bootstrapping the db,
	// because the client could be offline when trying to connect.
	let _ = db.bootstrap_db().await;
	})
	});

If libsql library is used in a single threaded environment, then it fails with following error:

can call blocking only when running on the multi-threaded runtime

This is happening due to incorrect use of block_in_place which should be used only in multiple threaded environments.
