Dependency update: update polar to 0.25

[WindSoilder]

Description

Update polar version to 0.25

Tests + Formatting

Make sure you've done the following, if applicable:

• Add tests that cover your changes (either in the command examples, the crate/tests folder, or in the /tests folder)
  • Try to think about corner cases and various ways how your changes could break. Cover those in the tests

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 --features=extra -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect to check that you're using the standard code style
• cargo test --workspace --features=extra to check that all tests pass

User-Facing Changes

If you're making changes that will affect the user experience of Nushell (ex: adding/removing a command, changing an input/output type, adding a new flag):

• Get another regular contributor to review the PR before merging
• Make sure that there is an entry in the documentation (https://github.com/nushell/nushell.github.io) for the feature, and update it if necessary

@elferherrera I know you are super busy, but if you have a bit of time it would be great if you could quickly review this PR.

If not, no problem, I will understand...

Thanks !
