add a more verbose description of operators (#7263)
# Description I was thinking that it may be helpful to have a more verbose description of our operators. Please let me know if you have better wording. Also, while not strictly considered an operator, i added `not` to avoid some confusion. <img width="1574" alt="Screenshot 2022-11-28 at 7 57 30 PM" src="https://user-images.githubusercontent.com/343840/204419666-7c4dbb43-26f5-4cd5-9a4e-a1555a9e700f.png"> # User-Facing Changes Adds description column # 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.
