fix format date based on users locale

[dmatos2012]

Description

Hi,

Fixes #10838, where before the date would be formatted incorrectly, and was not picking LC_TIME for time formatting, but it picked the first locale returned by the sys-locale crate instead. Now it will format time based on LC_TIME. For example,

// my locale `nl_NL.UTF-8`
❯ date now | format date '%x %X'
20-02-24 17:17:12

$env.LC_TIME = "en_US.UTF-8"

❯ date now | format date '%x %X'
02/20/2024 05:16:28 PM

Note that I also changed the default_env.nu as otherwise the Time will show AM/PM twice. Also reason for the chrono update is because this relies on a fix to upstream repo, which i initially submitted an issue

User-Facing 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)
• 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

use toolkit.nu  # or use an `env_change` hook to activate it automatically
toolkit check pr
