Refactor timestamp formatting in Git UI components to use chrono for local time calculations (#41005)

- Updated `blame_ui.rs`, `branch_picker.rs`, `commit_tooltip.rs`, and
`commit_view.rs` to replace the previous timestamp formatting with
`chrono` for better accuracy in local time representation.
- Introduced `chrono::Local::now().offset().local_minus_utc()` to obtain
the local offset for timestamp formatting.

Closes #40878

Release Notes:
- Improved timestamp handling in various Git UI components for enhanced
user experience.
