feat(next-international): use a regex to allow multiple interpolations

[cstrnt]

Right now it`s not possible to use a translation text that uses the same variable more than once, because only the first instance will be interpolated

Thanks for the PR! The only issue is that IE11 doesn't support replaceAll (but Next.js supports IE11, so we should do the same) - I think we can maybe use a regex with replace instead?
