Change the logic for displaying sci review notices

[rousik]

Until now, the pending-sci-review notice was included or not during the language import and this decision was based on the configuration in _config.yml. I have decided to make this a bit more flexible, always include the notice include in the markdown files and make the notice smarter and read the configuration and decide whether it should render the snippet or nothing. This will allow us to turn this on and off without having to rerun the language import from lokalise which I think is a better approach.

In order to speed things up I have bundled this with a flag-flip that enables pending-sci-notices for all languages by default. This should take effect next time translations are synced with head.
