Detailed message during core dumped (#7737)
# Description

In bash when a program crashes, it prints the reason for what happened:
```
$ ./division_by_zero
Floating point exception (core dumped)
$ ./segfault
Segmentation fault (core dumped)
```

Nushell always prints the same thing in this case:
```
> ./division_by_zero
nushell: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```

This PR adds more detailed error printing, like in bash:
```
> ./division_by_zero
Floating point exception: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```

I made this message format as an example:
```
Floating point exception: oops, process './division_by_zero' core dumped
```
Instead of `nushell:` it writes a meaningful message, but I can change
this format as per the suggestions.

I tested the change only on linux, but it should work on other unix
systems.

# User-Facing Changes

The error message only.

# 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.

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
