Type definitions are not published in @wp-playground/remote

[psrpinto]

In #1924 (with an extra fix in #1948) we started publishing @wp-playground/remote to npmjs.com. However, as @bgrgicak mentioned, the type definitions are not actually published with the package.

Package at npmjs

In the CI logs one can see that lerna indeed does not include the *.d.ts files:
