Better error message if env var is used as var (#9522)
# Description

This PR improves the error message if an environment variable (that's
visible before the parser begins) is used in the form of `$PATH` instead
of `$env.PATH`.

Before:

```
Error: nu::parser::variable_not_found

  × Variable not found.
   ╭─[entry #31:1:1]
 1 │ echo $PATH
   ·      ──┬──
   ·        ╰── variable not found.
   ╰────
```

After:

```
Error: nu::parser::env_var_not_var

  × Use $env.PATH instead of $PATH.
   ╭─[entry #1:1:1]
 1 │ echo $PATH
   ·      ──┬──
   ·        ╰── use $env.PATH instead of $PATH
   ╰────
```

# User-Facing Changes

Just the improvement to the error message

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the
standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
