[liferay workspace]provide tooling to better support extending themes using relative paths in package.json

[gamerson]

Lets say that you have two themes in a Liferay Workspace and wondering how to do it specifically in a CI build.

@jbalsas suggested the use of manually adding relative paths in the package.json. You can see I've added an example of that here:

https://github.com/gamerson/two-themes-test/blob/main/themes/extended-theme/package.json#L19
https://github.com/gamerson/two-themes-test/blob/main/themes/extended-theme/package.json#L45

Ideally, it would be good to add some more "tooling" up front to help developers in a Liferay workspace configure these relative paths.
