Fix date constructor in year padding test

[Copilot]

The test for year padding in test-format.ts was failing because new Date(Date.UTC(12, 5, 7, 12, 0, 0)) creates a date in year 1912, not year 12.

Changes

• Updated test to use ISO date string format: new Date("0012-06-07T12:00:00Z")
• This properly creates a date in year 12 to verify that Format.date() correctly pads years below 1000 to four digits

The test now correctly validates the yyyyMMdd format requirement for edge cases.

Pull request overview

This PR fixes a failing test in the date formatting module. The original test intended to verify that Format.date() correctly pads years below 1000 to four digits, but it was inadvertently testing year 1912 instead of year 12 due to incorrect use of the Date.UTC() constructor.

Key Changes:

• Fixed the date constructor in the year padding test to use ISO string format instead of Date.UTC(), ensuring the test validates year 12 as intended
• Updated yarn.lock with various dependency changes (appears unrelated to the test fix)
