Fixing NuLazyFrame/NuDataFrame conversion issues (#12538)
# Description

@maxim-uvarov brought up another case where converting back and forth
between eager and lazy dataframes was not working correctly:

```
> [[a b]; [6 2] [1 4] [4 1]] | polars into-lazy | polars append -c ([[a b]; [6 2] [1 4] [4 1]] | polars into-df)
Error: nu:🐚:cant_convert

  × Can't convert to NuDataFrame.
   ╭─[entry #1:1:49]
 1 │ [[a b]; [6 2] [1 4] [4 1]] | polars into-lazy | polars append -c ([[a b]; [6 2] [1 4] [4 1]] | polars into-df)
   ·                                                 ──────┬──────
   ·                                                       ╰── can't convert NuLazyFrameCustomValue to NuDataFrame
   ╰────
```

This pull request fixes this case and glaringly obvious similar cases I
could find.

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.
