Warning: Invalid DOM property `enterkeyhint`

[steida]

The problem
React 17 changed valid DOM property dev warning logic.
react-dom.development.js?61bb:67 Warning: Invalid DOM property enterkeyhint. Did you mean enterKeyHint?

How to reproduce
Just use TextInput.
https://codesandbox.io/s/zen-knuth-zn4ux

Expected behavior
Change this line supportedProps.enterkeyhint = returnKeyType; in TextInput. However, it would break React < 17 so I am not really sure how it should be fixed.
