Handle WP.org SVN missing tag warnings

[ramonjd]

What?

Follow up to #78476

Updates the Gutenberg plugin upload workflow so a missing WordPress.org SVN tag is recognized when svn list reports W160013 and E200009, not only E160013.

Why?

During the Gutenberg 23.4.0 stable release, the workflow checked whether tags/23.4.0 already existed before committing to the plugin SVN repository. The tag did not exist, but WP.org SVN returned:

svn: warning: W160013: URL 'https://plugins.svn.wordpress.org/gutenberg/tags/23.4.0' non-existent in revision ...
svn: E200009: Could not list all targets because some targets don't exist

The workflow only treated E160013 as "tag missing", so it failed before the release commit could run.

How?

Both stable upload paths now treat E160013, W160013, E200009, or non-existent output from svn list as exists=false. Other SVN errors still print the error and fail the workflow.

Testing Instructions

• Confirmed the observed WP.org SVN missing-tag output matches the new pattern.
• Confirmed an unrelated connection error does not match and remains fatal.
• Ran git diff --check.

actionlint was not installed locally, so I could not run full workflow linting.

Pull request overview

Updates the release workflow’s SVN-tag existence check so WP.org’s “missing tag” responses are correctly treated as exists=false, allowing the upload steps to proceed instead of failing early.

Changes:

• Expand the “missing tag” detection in svn list error output to include W160013, E200009, and non-existent (in addition to E160013).
• Apply the same detection logic to both stable upload paths (trunk+tag and tag-only).

I'm not sure we can manually test this, but the change looks good to me and matches the error/warning messages we saw today.

Looks worth trying to me!
