weekOfYear 'week' method doesn't seems to handle week number 53 for 'nb' locale

**Describe the bug**
Similar to the issue mentioned in #956, with a dutch locale (nl), the week number on the end of the year is incorrect.
Similar to the issue mentioned in #1030, with a dutch locale (fr), the week number on the end of the year is incorrect.

**Expected behavior**
When selecting the 'nb' locale and trying to return the weeknumber via days('2020-12-31').week(), the number returned is 1, while dutch calenders are supposed to return 53.

**Information**
Day.js Version: [v1.10.4]
OS: [MacOS]
Browser [Chrome 90]
Time zone: [CEST]

Start at the weekOfYear `week()` entry point and reproduce the `days('2020-12-31').week()` case with the `nb` locale. Compare the returned value with the reported expected value of 53, and consider the issue complete when the locale handles week 53 correctly without regressing related week-number behavior.
