Array of Tables `remove` does not return the removed table

I am trying to push a specific table to the top in the array, but unable to do so.

Example code:
```rust
fn push_to_top(array: &mut ArrayOfTables, index: usize) {
    let table = array.remove(index); // <--- This does not return the removed table.
    array.push(table);
}
```

`toml_edit::Array` already seems to return the removed value, so this would be nice for API consistency.
