Add multilanguage support

I changed the field to be translatable. I'm not using this module on any multilingual sites, can you let me know if anything else is needed?

@DieterHolvoet Hello, I will try the field to see how it works.

It would be possible to configure the field as seen here

You can't edit the field because it's a base field, but you should be able to enable translation on /admin/config/regional/content-language.

@DieterHolvoet Hello, I understand and this is a query, let's say if I want I have 3 types of content and in all 3 I use co author but I only want the translation to be activated in one of them, is that possible and the other 2 continue without translation, is that possible?

Yes, you can configure this per node type on /admin/config/regional/content-language, just like you can for e.g. the author field.
