Encode plugin: add support for Yaml

A good one to add!

Can you add two test cases for this to Drupal\Tests\tamper\Unit\Plugin\Tamper\EncodeTest?

Maybe it would also be good to use a switch() statement here. Because now if some module or library would define the function yaml_encode(), then that would be called instead.

I see also that the Tamper plugin would allow you to call any function that is defined in your config file, instead of only the ones provided by the option list. That doesn't sound like desirable functionality. Fixing that is technically out of scope for this issue, but by switching to switch() that side effect would be resolved as well.

I've added 2 tests. BTW. the json encode and decode variations don't have tests either, maybe something for another follow-up. Just like the switch from #5

Alright. Fair enough. I merged this and created a follow-up: 📌 Encode plugin: only call function from the available options Active .
