#8027 Hide implementation details in invalid cd call (#8049)

# Description

[GH issue](https://github.com/nushell/nushell/issues/8027)

The current error message for a cd command includes a Debug output of
the `io::Error` being returned from `canonicalize_with`, so it's been
replaced with a more user friendly and readable depiction of the error.

# User-Facing Changes

As described in the issue, I've changed the error message for a cd into
a directory that does not exist from:
```
/home/rdevenney/projects/open_source/nushell〉cd asdfasdf                                                                               02/11/2023 08:59:59 PM
Error: nu:🐚:directory_not_found (link)

 × Directory not found
   ╭─[entry #2:1:1]
 1 │ cd asdfasdf
   ·    ────┬───
   ·        ╰── directory not found
   ╰────
  help: IO Error: Os { code: 2, kind: NotFound, message: "No such file or directory" }
```
To:
```
/home/rdevenney/projects/open_source/nushell〉cd asdfasdf                                                                               02/11/2023 08:58:38 PM
Error: nu:🐚:directory_not_found (link)

  × Directory not found
   ╭─[entry #1:1:1]

   ·    ────┬───
   ·        ╰── directory not found
   ╰────
  help: IO Error: DirectoryNotFound
```
# 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` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# 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.
