fix: plural pseudolocalization with offset

[MartinCerny-awin]

I have improved RegEx for plurals. It now correctly escapes plural with offset. This is fix for #743, but it does not close it as there is need to escape other React components like Select, SelectOrdinal & DateFormat

I was not able to test the code because of this #886
