How about supporting TypeScript file?

[munierujp]

Writing configuration files in TypeScript is useful in preventing typographical and type errors.

import type {Config} from 'jest';

const config: Config = {
  verbose: true,
};

export default config;

In cosmiconfig, TypeScript is supported by the third-party cosmiconfig-typescript-loader.

I have looked at this again and many of the use cases will be the type to the whole Config like Config.
Therefore, we think that it would be less expensive to use TSDoc for .js.

@azu I have understood the disadvantages of supporting TypeScript. Thank you!
