Handle relative paths correctly on polars to-(parquet|jsonl|arrow|etc) commands (#12486)
# Description

All polars commands that output a file were not handling relative paths
correctly.

A command like
``` [[a b]; [6 2] [1 4] [4 1]] | polars into-df | polars to-parquet foo.json``` 
was outputting the foo.json to the directory of the plugin executable. 

This pull request pulls in nu-path and using it for resolving the file paths.

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.
