fix: Release workflow working directory (#208)

## Description

Fixes working directory in which dependencies are installed (release
workflow didn't pass because of the patch in the `example` app that is
not accepted by npm but it was included in yarn.lock after deps
installation in the root as it was hoisted from the example app)
