Declare license in package.json of published packages

[Jeldrik Hanschke]

The license is only declared in package.json at workspace root but not in the package.json of the published packages. Would be great if we could add it their as well as many tools rely on that information (e.g. pnpm licenses ls).

Likely a duplicate of #1463.
