Type definitions in TouchRipple.d.ts are not in sync with TouchRipple.js

Type definitions in TouchRipple.d.ts are not in sync with TouchRipple.js
The TouchRippleClassKey is defined as
export type TouchRippleClassKey =
| 'root'
| 'wrapper'
| 'wrapperLeaving'
| 'wrapperPulsate'
| 'ripple'
| 'rippleVisible'
| 'ripplePulsate';

While the one actually implemented in TouchRipple.js has "child" instead of "wrapper", "childLeaving" instead of "wrapperLeaving" and "childPulsate" instead of "wrapperPulsate"

• [ x] This is a v1.x issue (v0.x is no longer maintained).
• [ x] I have searched the issues of this repository and believe that this is not a duplicate.
