Year + Week wrong calculation

**Describe the bug**
Using dayjs setting year and week brings wrong date

**Expected behavior**
Setting dayjs().year(2024).week(1) should give you a day in the first week of 2024. It gives you a day in 2025 instead.
Everything returns cool if you reset the month (e.g. dayjs().year(2024).startOf('year').week(1))

**Information**
- Day.js Version: v1.11.10
- OS: Ubuntu
- Browser: Firefox 120.0.1 (64 bit)
- Time zone: GMT+01:00 (Rome)

No source file or test is named. Reproduce the exact dayjs().year(2024).week(1) chain, compare it with the startOf('year') example, and trace the year and week calculations; done means the first-week result is correct and covered by a regression test.
