For this we must raise the twig min. version in composer.jsonto 3.12.0

Raised to Twig 3.12

3.12 was release in August 2024, not sure if that bump is considered to be too big?

https://github.com/twigphp/Twig/releases/tag/v3.12.0

I open a PR to only fix the AbstractNodeVisitor deprecations #520. I am not a fan of big prs with to many changes.

i also agree with @rvanlaak but we should only support twig releases for 1 year. What do you think @bocharsky-bw?

I moved AbstractNodeVisitor here to this bundle, deprecation about Twig's AbstractNodeVisitor beeing deprecated should be therefore resolved.

I also levereaged existence of this class to add metod to add functionality for getting the value from node, and here is specific method distinguished by Twig version - which should also remove deprecations and ensure older Twig version support

You can simply put your getValueFromNode() into a trait. With a comment that it can be removed when we raise the dependency of twig to 3.12.
We did not need the wrapper code doEnterNode doLeaveNode see my pr.
