fix(typescript) remove extraneous imports

[arichiv]

#953 adds a bunch of imports to fix an error in typescript type expansion. They should be removed at some point.

Each one looks like:

import {
  [...]
  // @ts-ignore TODO(issues/955) Remove once possible
  RippledComponentProps, // eslint-disable-line @typescript-eslint/no-unused-vars
} from '@material/react-ripple';

Each one should be reduced to:

import {
  [...]
} from '@material/react-ripple';

@moog16 I traced this to a typescript error not unlike microsoft/TypeScript#24874 (cc: @weswigham)

If we do not explicitly import RippledComponentProps the resulting typefile attempts a relative import at the bottom (import("../ripple").RippledComponentProps).

If we do explicitly import RippledComponentProps (and use/export it as required to avoid lint errors) the resulting typefile is able to directly use the imported type (RippledComponentProps).

This appears to be an issue in typescript resolution/expansion itself. The import at the top is left alone, but the generated one at the bottom will default to a relative import.

Thanks for doing some more investigation. It sounds like this is a TypeScript bug then? We can leave this open until there is a fix and we update to that version. How does that sound?
