FIX: redirect to encode base64 as hash bash64 is deprecated (#8351)
# Description
i tried yesterday to `encode` with an invalid character set and this is
what i got
```bash
>_ {alg: "HS256", type: "JWT"} | to json -r | encode base64 --character-set invalid-character-set
Error:
  × value is not an accepted character set
   ╭─[entry #11:1:1]
 1 │ {alg: "HS256", type: "JWT"} | to json -r | encode base64 --character-set invalid-character-set
   ·                                                                          ──────────┬──────────
   ·                                                                                    ╰── invalid-character-set is not a valid character-set.
Please use `help hash base64` to see a list of valid character sets.
   ╰────
```

but `hash base64` is now a deprecated command, see `help hash base64`.

=> **this PR changes the error message to mention `help encode base64`,
where the list of valid character sets is, instead**

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.
