issue with en_AU locale

[alec000inspired]

Overview Description

When I use the en_AU locale, the date format for 2023-12-31 places it into W1 of 2023. I would expect this to be W53 of 2023 or possible W1 of 2024.

Steps to Reproduce

import datetime
import babel
import babel.dates
foo = babel.dates.format_date(datetime.date(year=2023, month=12, day=31), format="'W'w YYYY", locale='en_US')
bar = babel.dates.format_date(datetime.date(year=2023, month=12, day=31), format="'W'w YYYY", locale='en_AU')
print(foo)  # W53 2023 (correct)
print(bar)  # W1 2023 (incorrect)

Actual Results

'W1 2023'

Expected Results

'W53 2023'
