ansi name for clear-scrollback code (#14184)
Related to #14181

# Description

Our understanding of `ESC[3J` has apparently been wrong. And I say "our"
because I posted a [Super User
answer](https://superuser.com/a/1738611/1210833) a couple of years ago
with the same misconception (now fixed). In addition, the [crossterm
crate
doc](https://docs.rs/crossterm/latest/crossterm/terminal/enum.ClearType.html)
is wrong on the topic.

`ESC[3J` doesn't clear the screen plus the scrollback; it *only* clears
the scrollback. Reference the official [Xterm Control Sequences
doc](https://www.xfree86.org/4.8.0/ctlseqs.html).

> CSI P s J
> 
> Erase in Display (ED)
> 
> P s = 0 → Erase Below (default)
> P s = 1 → Erase Above
> P s = 2 → Erase All
> P s = 3 → Erase Saved Lines (xterm)

This also means that:

```nu
$"(ansi clear_entire_screen_plus_buffer)"
```

... doesn't.

This PR updates it to `ansi clear_scrollback_buffer` (short-code remains
the same).

# User-Facing Changes

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.
