InputNumber: (Germany) second step of currency can't changed

[tugcekucukoglu]

First, delete all the input, type some numbers, and then type a comma. The second step of the currency will not change anymore.

I think this is related: #5548

@melloware
It's most likely caused here, If separated by comma the isDecimalSign can't judge correctly
the primeng worked, I still haven't figured out why. The codes seem to be the same
https://github.com/primefaces/primereact/blob/master/components/lib/inputnumber/InputNumber.js#L866C24-L866C24

// isDecimalSign return false
const newSelectionEnd = selectionEnd + Number(isDecimalSign(value) || isDecimalSign(insertedValueStr));

How about changing it to this?
@melloware @tugcekucukoglu

const isDecimalSign = (char) => {
    if (_decimal.current.test(char) || _decimal.current.test(char.toString().replace(".",","))) {
        _decimal.current.lastIndex = 0;

        return true;
    }

    return false;
};

@kl-nevermore but won't that check for decimal or comma regardless of Locale?
