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

# Tests + Formatting

+ 1 failure test

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
