REFACTOR: clean the root of the repo (#9231)
# Description
i've almost always wanted to clean up the root of the repo, so here is
my take at it, with some important advice given by @fdncred 😌

- `README.release.txt` is now gone and directly inline in the
`release-pkg` script used in the `release` *workflow*
- `build.rs` has been moved to `scripts/` and its path has been changed
in
[`Cargo.toml`](https://github.com/amtoine/nushell/blob/refactor/clean-root/Cargo.toml#L3)
according to the [*Build Scripts*
section](https://doc.rust-lang.org/cargo/reference/build-scripts.html#build-scripts)
of *The Cargo Book*
- i've merged `images/` into `assets/` and fix the only mention to the
GIF in the README
- i've moved the `docs/README.md` inside the main `README.md` as a new
[*Configuration*
section](https://github.com/amtoine/nushell/tree/refactor/clean-root#configuration)
- the very deprecated `pkg_mgrs/` has been removed
- all the `.nu`, `.sh`, `.ps1` and `.cmd` scripts have been moved to
`scripts/`

### things i've left as-is
- all the other `.md` documents
- the configuration files
- all the Rust and core stuff
- `docker/`
- `toolkit.nu`
- the `wix/` diretory which appears to be important for `winget`

# User-Facing Changes
scripts that used to rely on the paths to some of the scripts should now
call the scripts inside `scripts/` => i think this for the greater good,
it was not pretty nor scalable to have a bunch of scripts in the root of
our main `nushell` 😱

*i even think we might want to move these scripts outside the main
`nushell` repo*
maybe to `nu_scripts` or some other tool 👍 

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
-  `toolkit test`
-  `toolkit test stdlib`
