Add workflow for releases (#3760)

## Description

This PR adds workflow that will publish new versions of **Gesture
Handler** to `npm`. This is similar to [react-native-screens
CI](https://github.com/software-mansion/react-native-screens/blob/15f83cf00b2d46c17c8e0f4c157c76f10bb57d53/.github/workflows/npm-screens-publish-nightly.yml),
but this one will publish stable releases.

> [!NOTE]
> We will dive deeper and check how to make this CI publish both,
nightly and stable releases. For now we need this for stable release, so
we want to make sure it works without any problems.

## Test plan

Downloaded artifact from CI.
