`dayjs('0099-11-11').get('year')` get '1999' instead of '99'

**Describe the bug**
The year is `1999`

**Expected behavior**
The year is `99`.

Although we may not handle years less than 4 digits, this could be useful for historical dates.

**Information**
- Day.js Version [e.g. v1.0.0]
1.11.10
- OS: [e.g. iOS]
macOS
- Browser [e.g. chrome 62]
Chrome 119
- Time zone: [e.g. GMT-07:00 DST (Pacific Daylight Time)]
GMT+9:00 (Japan Standard Time)

The issue names no files, tests, or entry points. Start by reproducing dayjs('0099-11-11').get('year') with Day.js 1.11.10, then trace the date parsing and year retrieval paths. Done means the value is 99 for this input while existing date behavior remains intact.
