[Syncfusion_flutter_datepicker] Day Cells Semantics - Resource for change language

[guilhermedaldim]

Use case

Hi, thanks for your package, it's very great.

I need change the language cell semantics to pt_BR in the syncfusion_flutter_datepicker for flutter web.

I researched in the documentation and I follow the instructions for change language, I configure that, but in the cell's day doesn't changed.

Proposal

My proposal is the package change this when the language configure is changed.

Thanks for your package and your support.
