Capitalize "Set featured image" media button on Media Modal

All the button on WordPress are in capitalize form except this "Set featured image" button so there should be consistency on all button.

Not capitalize

[SergeyBiryukov]

There's a number of other non-capitalized primary buttons in media modal:

• Insert into post
• Create a new gallery
• Create a new playlist
• Create a new video playlist

As well as in other parts of WordPress:

• I understand
• Restore image
• Go back
• Take over
• Back to theme sources

Most of primary buttons are indeed capitalized, but I don't think it's necessary to capitalize them all. Thoughts?

A thought (not A Thought):

Set Featured Image - because "Featured Image" is a terminus technicus inside WP, but
Add new category, because it's generally spoken.

Keeping this logic most of them would not need to be capitalized.

I think I am right in saying this needs design feedback, not an actual design. I am going to add that keyword.
