First day of the week is incorrect

[ebicoglu]

Describe the bug
The first day is Tuesday which is incorrect.
Must be culture-specific or Monday.
Maybe related to #1997

Hello @ebicoglu,
have you tried to use FirstDayOfWeek setting?

Edit : (Independent of FirstDayOfWeek, you are right the day is totally wrong, day 6 is a monday, even if it started on tuesday, it should be day 7)

In the meantime, I went to take a look at the translation since I knew I had seen this visually starting on Monday by default when localization is set to my native language which is Portuguese. I noticed the translations are jumbled up:

(Should be )

"Monday": "Segunda-feira",
"Tuesday": "Terça-feira",
"Wednesday": "Quarta-feira",
"Thursday": "Quinta-feira",
"Friday": "Sexta-feira",
"Saturday": "Sábado",
"Sunsay": "Domingo",

(I can go ahead and correct the pt translations later...)
@stsrki can you check if the same happens for other translations?

The days are also shifted for icelandic https://github.com/Megabit/Blazorise/blob/447d4773575f1c1f2530d4189c93935ac4141133/Source/Blazorise/Resources/Localization/DatePicker/is.json

Mondays are shown as Sunday etc. I created a PR for the changes.

Yeah, it seems it is a copy-paste mistake. We'll fix it. @David-Moreira you can fix Portuguese
