Categorification: move uncategorized String commands to Category::Strings (#9931)
In an effort to go through and review all of the remaining commands to
find anything else that could possibly
be moved to *nu-cmd-extra*

I noticed that there are still some commands that have not been
categorized...

I am going to *Categorize* the remaining commands that still *do not
have Category homes*

In PR land I will call this *Categorification* as a play off of
*Cratification*

* str substring
* str trim
* str upcase

were in the *default* category because for some reason they had not yet
been categorized.
I went ahead and moved them to the

```rust
.category(Category::Strings)
```

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.
