Allow typescript project as parameter

Problem

While developing any project you expect the tools to work by default when type checking and linting, this includes this tool implementation in the IDE. Those tools use tsconfig.json by default which is something expected.

This configuration looks like this:

# tsconfig.json
{
  ...some typescript configuration
  "include": ["src/**/*", ".jest/**/*", ".storybook/**/*"],
}

This configuration will cause package-build library to compile all files included in the Typescript configuration. This means it will include in the bundle useless files for distribution like unit tests, storybook stories and test helpers.

To avoid this we should be able to define a different file for configuration like tsconfig.build.json only including library entrypoint, usually src/index.ts.

# tsconfig.build.json
{
  ...some typescript configuration
  "include": ["src/index.ts"],
}

This configuration will avoid transforming useless files into the bundle but allow the tools to use the root tsconfig.json as a reference.

Just a nit suggestion
