v0.1.1: Include tsconfig.json in package

tsconfig.json's `extends` option uses legacy module resolution [1] and,
as a result, does not honor package.json's `exports` field. This change
publishes tsconfig.json at the root of the package so that it can be
imported by consumers via `"extends": "bitumen"`.
