What is the current behavior/state of the project?
The project does not support ESM build because of an incorrect TS type definition and yields the following error

import MatchMediaMock from "jest-matchmedia-mock";
new MatchMediaMock();
// ts-error: Type 'typeof import(".../node_modules/jest-matchmedia-mock/dist/matchmedia-mock")' has no construct signatures.

What is the desired behavior?
Having the TS type definition reflect the runtime behavior when imported in an ESM module.
