Incompatibility with Kirby 3.6 : Str::template() parameters deprecated

[ralfgoeke]

Describe the bug

In Kirby 3.6.0 beta 3 an error is thrown in …/vendor/mzur/kirby-uniform/src/Actions/EmailAction.php Line 112

Str::template(): the parameters $fallback, $start and $end have been deprecated and throw a deprecation warning. Use instead an $options array with fallback, start and/or end keys as third parameter.

This seems to work, but my not so overwhelming PHP knowledge suggests to not trust this blindly.^^

$subject = Str::template($this->option(
  'subject',
  [
    'start' => I18n::translate('uniform-email-subject'),
    'end' => $templatableItems,
    'fallback' => '',
  ]
));

I've released a new version with a fix.
