Translation issue in videos added to Gallery and Media paragraphs

[piotrsmykaj]

When adding a media remote_video in Gallery or Media paragraph and when the video is translated into several languages
Then the translated video has to be shown to the user in the respective language.
But, it only shows the video in English even in other translation pages.

To reproduce the issue it's needed to create a node in a specific order:

Make sure you have a media remote_video in EN and X translation
Add Page in EN without Gallery
Add X translation to the Page
Add Gallery to the EN Page
View the Page in X translation and the played Video will be in English, but it should be in X translation
In this case, both paragraph records (for both translations) in paragraph_item_field_data are created with langcode EN.

when adding a Page in EN with Gallery, then paragraph records are created with EN and X langcode values and the problem doesn't happen.
