try to fix datetime-diff for ms, us, ns (#15537)
# Description

This PR tries to fix the datetime-diff custom command so that it
includes ms, us, ns.

Difference in the banner in 2 separate starts.

### Old
```nushell
It's been this long since Nushell's first commit:
5yrs 10months 29days 9hrs 1min 47secs
```

### New
```nushell
It's been this long since Nushell's first commit:
5yrs 10months 29days 9hrs 1min 22secs 49ms 885µs
```

There should be ns above on the new one, not sure why there isn't. It
could have something to do with how the banner works but i'll save that
for another PR.

🤔 It could be because there are no fractional seconds in the math?
`datetime-diff (date now) 2019-05-10T09:59:12-07:00`. However, I'm not
sure why `date now` has no nanoseconds. Oh, wait. I think that's because
MacOS doesn't have nanosecond precision?
```
❯ ^date +%s.%N
1744251636.365003000
```

<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

# 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` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` 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
> ```
