PR Summary

  This includes tags indicating when the changes were made.

• Inclusion of a new 'render' method in class-export.php file
  Improved documentation is provided for this new feature showing when it was introduced.

• Removal of unused imports in class-import.php file
  These imports were no longer necessary and their removal streamlines the code.

  The new 'class-test-export.php', 'class-test-import.php', and 'class-test-migrate.php' files will help to validate that the system is working correctly.

@carstingaxion I also discovered some things we should add to distignore. Updated PR with those. Your zip file helped me discover it :-D

Hmmmm, still showing test and jest.config.js...

Maybe this line within the checkout step could be the problem:

gatherpress/.github/workflows/playground-preview.yml

Line 36 in 188c441

ref: ${{ github.ref }}

This should be github.head_ref I guess.

Maybe this line within the checkout step could be the problem:

This has been another can of worms, but at least this step number 147 is taken now too. Let’s see how far we can get. I illustrated my last test-PR #775 with some screenshots, to show that the checkout grabs the correct ref before doing the build.
