allow ansi strip
to work better on other nushell values (#11781)
# Description This PR help `ansi strip` work on more nushell values. It does this by converting values like filesize and dates to strings. This may not be precisely correct but I think it does more what the user expects. ### Before ![image](https://github.com/nushell/nushell/assets/343840/768ffbb2-e3d7-424e-8e3b-1d20c9aa7d91) ### After ![image](https://github.com/nushell/nushell/assets/343840/6141aebb-481f-45a9-9cb7-084ca9ca1ea5) # User-Facing Changes <!-- 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 std testing; testing run-tests --path crates/nu-std"` 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 > ``` --> # 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. -->
