improve assertion error messages in std assert (#10551)
should close #10549
# Description
this PR is twofold
- uses `to nuon --raw` in the error messages to make sure #10549 is
solved and makes a difference between `"1"` and `1`
- tries to introduce slightly better errors, i.e. by putting left /
right on new lines => this should hopefully help when the values become
a bit big 😋
# User-Facing Changes
the original issue:
```nushell
> assert equal {one:1 two:2} {one:"1" two:"2"}
Error: × Assertion failed.
╭─[entry #3:1:1]
1 │ assert equal {one:1 two:2} {one:"1" two:"2"}
· ───────────────┬───────────────
· ╰── These are not equal.
Left : '{one: 1, two: 2}'
Right : '{one: "1", two: "2"}'
╰────
```
a sample for all the assertions and their new messages
