The sourcemaps which are published by this module are broken

Issue description

The sourcemaps which are published by this module are broken

Expected Behavior

The sourcemaps are either not present, or refer to files which exist and are contained in the typeorm package.

Actual Behavior

Currently the sourcemaps published to NPM refer to files outside the package. This confuses other tooling which is trying to use the sourcemaps, like C8. For example, /index.js.map in the NPM package refers to ../../index.ts which is not only not inside the typeorm package, it's likely inside the application which installed the package.

Steps to reproduce
