feat: upstream sync workflow V2

[asdolo]

What does this do?

• Remove the now deprecated upstream-to-pr.yml workflow.
• Add the new sync-with-upstream.yml workflow with the following changes:
  • Change schedule to run the workflow from Monday to Friday, instead of every day.
  • Add a new template-version input to the workflow to manually indicate to which upstream version the template needs to be updated.
  • Update needed permissions of both workflow and Personal Access Token to the minimum, using a fine-grained token.
• Backport some of the new features to sync-with-template.yml workflow.
• Minor changes to the cli script.

Why did you do this?

To introduce the following new features:

• Integrate changes from the latest release by default: The workflow now defaults to integrating changes from the latest stable release instead of pulling from the upstream master branch, which can be unstable.
• Integrate changes from a specific release: Enables selecting a specific release version for integration. This allows for incremental upgrades, avoiding large pull requests and facilitating staggered updates. The workflow can be run manually by specifying the desired release in the release field:
  
• Add ignored files and directories: Introduced a feature to exclude specific files and directories during updates. For instance, the ios and android directories can now be ignored, as they are no longer pushed to the repository.

Who/what does this impact?

New and current users of the template. Please read instructions in .github/project-workflows/sync-with-template.yml to setup the new workflow.

How did you test this?

I created a private fork of the template, pushed the new workflow to the master branch (so it can be used) and tested different scenarios.

Do you think a check to validate if the template-version input is a valid version string?

Do you think a check to validate if the template-version input is a valid version string?

@fernandatoledo I tried with an invalid string ("hello") and the whole workflow just fails saying "fatal: couldn't find remote ref hello", which is what we want. What do you think?
