feat: add action for checking upstream for changes

[asdolo]

What does this do?

• This PR adds a new GitHub Action to check for upstream (obytes) changes and it creates a new branch and a PR with those changes. The action will automatically be triggered daily. It also allows for manual/API triggered checks (workflow_dispatch).
• It also modifies the cli app so new projects created with the latest cli version will also have this action, which will check if Rootstrap's Template repository has new changes to be merged to their project.

Why did you do this?

To automate, notify and control what changes we want to merge from the upstream repository (Obytes) to our template.

Who/what does this impact?

• Template Maintainers because, starting from now, new PRs will be automatically created and they'll have the responsibility to review them, decide and debate which changes from Obytes we want to include in our Template and fix possible merge conflicts.
• Developers using our Template in their projects.
