Translations are unpublished and can't be changed

I have added a PR to expose the published field. Please review.

scott_euser → changed the visibility of the branch 3512340-translations-are-unpublished to hidden.

scott_euser → changed the visibility of the branch 2.0.x to hidden.

Thanks for the contribution! The most common use case (I believe) is global settings for things that appear on all pages, so having published checkbox everywhere isn't ideal as it complicates the user interface when it normally does not matter (but of course that default for translation is unpublished is proper bug).

So we have a precedent for optionally showing/hiding things in the UI like this:

So I think on top of your current MR we should ideally:

1. Maintain the status quo of published being hidden - ie, update hook setting hide_published true
2. Let people opt-in to managing published status - ie, new hide_published in SiteSettingsConfigForm
3. Default to published for new translations if managing published status is disabled - I believe in SiteSettingEntity field status can be with ->setDefaultValue(TRUE)

Thank you!
