Cast captured variables to string

The issue here is very similar to efabrica-team/phpstan-latte#398 and the workaround is a bit different although type-casting would also work for the case reported in that bug.

Fixes errors like "Parameter #2 ...$args of method MichalSpacekCz\Templating\Filters::format() expects int|string, Latte\Runtime\Html|string|false given."
