Suggestion: Replace Submit Contribution with "Apple pay" button where applicable

I was trying out 6.6 brach, I have noticed the "apple pay" button appears in the middle of the form. I have post-profile form in that contribution page. So I can see both the button, which seems confusing.

Apple pay doesn't seems to work where multiple payment processor is installed. I know it's still work in progress, just caught my eye. Thanks
