Error on negative argument to last (#7184) ...

# Description

- Error on negative argument to `last`
- Add test for negative value in last

Follow-up for #7178

# User-Facing Changes

Breaking change:

even before #7178 `last` returned an empty `list<any>` when given
negative indices.
Now this is an
[error](https://docs.rs/nu-protocol/latest/nu_protocol/enum.ShellError.html#variant.NeedsPositiveValue)

Note:
In #7136 we are considering supporting negative indexing
