[PTRun][Calc] Add support for different list separators based on locale

[PesBandi]

Description of the new feature / enhancement

In cultures where the list separator isn't a comma, the only way to use functions that take multiple arguments is this weird workaround where you surround a comma with spaces (i.e. max(2,7 , 3,5)). I propose replacing the current culture's list separator with the target culture's (en-US) separator, so that you can do max(2,7;3,5).

Scenario when this would be used?

When the current culture uses a different list separator than ,

Your contribution is welcome and thank you for your work on this. Feel free to open a PR. If you have any further questions don't worry to ask them.

What's your plan? Setting or simultaneously usage support or general switch of the character?

Hi @htcfreek, I was thinking I'd put it in NumberTranslator, next to where the decimal symbol is replaced.

PowerToys/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.Calculator/NumberTranslator.cs

Lines 123 to 126 in 809791d

	outputBuilder.Append(
	decimal.TryParse(token, NumberStyles.Number, cultureFrom, out number)
	? (new string('0', leadingZeroCount) + number.ToString(cultureTo))
	: token);

I'm on my way to open the pull request, so maybe check it out there :)
