[web] [fix] remove border-radius in input type="submit"
Summary:
I've got this error in my VSCode for a while. Not sure why -webkit prefix was used here, I'm assuming it's just really old css. Border radius is a widely supported css property. https://developer.mozilla.org/en-US/docs/Web/CSS/border-radius#browser_compatibilit)
Update:
We no-longer use these css declarations in the code, so I'm removing them.
