This PR fixes an issue where, for custom values, the `//` operator was
incorrectly mapped to `Math::Divide` instead of `Math::FloorDivide`.
This PR also fixes the same mis-mapping in the `polars` plugin.

```nushell
> [[a b c]; [x 1 1.1] [y 2 2.2] [z 3 3.3]] | polars into-df | polars select {div: ((polars col c) / (polars col b)), floor_div: ((polars col c) // (polars col b))} | polars collect
╭───┬───────┬───────────╮
│ # │  div  │ floor_div │
├───┼───────┼───────────┤

```

**Note:** the number of line changes in this PR is inflated because of
auto-formatting in `nu_plugin_polars/Cargo.toml`. Substantively, I've
only added the `round_series` feature to the polars dependency list.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Breaking change: users who expected the operator `//` to function the
same as `/` for custom values will not get the expected result.

# 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
> ```
-->
No tests were yet added, but let me know if we should put something into
one of the polars examples.

# 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.
