Optimize SVN tag addition in GitHub workflow

This commit significantly optimizes the process of adding a new tag to the SVN repository in our GitHub Workflow.

Previously, our process involved checking out the entire tags directory from the SVN repository, which led to increased execution time and failure points when the tags directory was filled with numerous versions.

We've resolved this issue by leveraging the svn import command, which allows us to directly add a new directory to the tags directory without checking out the existing directories first. This results in faster and more reliable workflow execution, particularly when dealing with repositories that have accumulated many tagged versions.

The changes made include:

    Removing the step to checkout Gutenberg tags from the WP.org plugin repository.
    Adding a new step that uses the svn import command to directly add a new version directory to the SVN repository. This is achieved without the need to checkout all existing directories under tags/.
    Removing the step to checkout the new Gutenberg tag as it's not needed anymore.
