Adjust smart date twig function to factor in timezone

I'm not sure about what needs to be implemented. I added the possibility to set a timezone from twig (smart_date_format('extended', 'UTC')). But if we leave it empty they use core DateFormatter::format and set the default timezone.

Hello @mandclu,

Could you please review this?

Thank you

Thanks for the work on this. Moving this to a supported branch seems to have fixed the CI errors, so merged this in.
