chore(docs): fix wrong Nargo.toml workspace examples (#4822)

# Description

## Problem\*

Resolves #4805

## Summary\*

This PR fixes the issue found by @iAmMichaelConnor in #4805, where the
example Nargo.toml content for [workspace] has
 members with wrong paths. 

Since the structure has Nargo.toml inside the `crates` folder, then
`members` should direct to folders inside `crates`.
``` file structure
├── crates
│   ├── a
│   │   ├── Nargo.toml
│   │   └── src
│   │       └── main.nr
│   └── b
│       ├── Nargo.toml
│       └── src
│           └── main.nr
├── Nargo.toml
└── Prover.toml
```

## Additional Context

All nargo versions I've tested with, from v0.19.0 to v0.27.0, return
`Cannot read file /home/sihanouk/crates/crates/a/Nargo.toml - does it
exist?` without the fix.
