This PR updates the Blogging Quickstart front page card to have internationalized text since we are planning to open it for all users instead of just English-speaking ones.
Testing instructions
Check out this PR to local.
Sandbox the API, and comment out lines 98-100 of wp-content/lib/home/cards.php (which hides the card for non-English speakers).
Verify that the text displays on the Blogging Quickstart card properly – in English at first, and then in all Mag16 languages once the translations have gone through after merge.
