Related to #8119.
Should address the review comment by @sholderbach from #8119.
# Description
this PR adds the output to the new example for the `with-env` command
introduced by #8119.
```bash
with-env {X: "Y", W: "Z"} { [$env.X $env.W] }
```
should output
```bash
["Y", "Z"]
```
hence the proposition from @sholderbach, i.e.
```rust
Some(Value::list(
vec![Value::test_string("Y"), Value::test_string("Z")],
Span::test_data(),
))
```
