Move external actions and workflows locally

[YaroShkvorets]

Right now, our CI/CD relies on github actions and workflows hosted by The Guild in the corresponding repos and in their shared config

There are potential issues with that:

• NPM/GitHub tokens could leak
• breaking changes
• repos going private

This PR addresses that. No functional changes.

1. Reusable workflows and composite actions moved into the repo itself in .github directory
2. Forked actions repos:

• https://github.com/pinax-network/changesets-snapshot-action
• https://github.com/pinax-network/changesets-release-action
• https://github.com/pinax-network/changesets-dependencies-action
