Pass $decimals argument to number_format_i18n filter

[alpipego]

Filtering the value passed from number_format_l18n is limited as one can only guess the value for $decimals.

$decimals should be passed to the filter, to make it more useful.

Formatting: Add the $number and $decimals arguments to the number_format_i18n filter.

Fixes #41505

@alpipego Thanks for the patch. I added the raw $number parameter too, as the formatted number on its own isn't very useful if you're re-formatting the number.

Ah, that's great, hadn't thought about that. Thanks!
