Translated months names off

[PascaleBeier]

Hello,

I encountered an issue with the following code:

foreach (range(1,12) as $month) {
    echo \Carbon\Carbon::now()->setMonth($month)->getTranslatedMonthName() . '<br>';
}

Carbon version: 3.8.0

PHP version: 8.3.12

I expected to get:

January
February
March
April
May
June
July
August
September
October
November
Dezember

But I actually get:

January
March
March
May
May
July
July
August
October
October
December
December

Examples:

This works:

foreach (range(1,12) as $month) {
    echo \Carbon\Carbon::now()->setDay(1)->setMonth($month)->getTranslatedMonthName() . '<br>';
}

Seems to be a duplicate of #2317

Hello, if you want to get translated month name from month number, now is irrelevant, you'd better directly create a date from this number rather than creating an object then modifying it:

foreach (range(1, 12) as $month) {
    echo \Carbon\Carbon::create(2000, $month, 1)->getTranslatedMonthName() . '<br>';
}

2000 is a completely arbitrary year, any number would work the same.
