Only run from_string conversion on strings (#14509)
# Description

#14249 loaded `convert_env_values()` several times to force more updates
to `ENV_CONVERSION`. This allows the user to treat variables as
structured data inside `config.nu` (and others).

Unfortunately, `convert_env_values()` did not originally anticipate
being called more than once, so it would attempt to re-convert values
that had already been converted. This usually leads to an error in the
conversion closure.

With this PR, values are only converted with `from_string` if they are
still strings; otherwise they are skipped and their existing value is
used.

# User-Facing Changes

No user-facing change when compared to 0.100, since closures written for
0.100's `ENV_CONVERSION` now work again without errors.

# Tests + Formatting

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting

Will remove the "workaround" from the Config doc preview.

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.
