* Updated "expected" images for screenshot tests.

* dropme - show node.js version active on github CI

* CI - add missing setup-node for typescript tests

* CI - use actions/checkout@v3 for typescript tests

* Revert "Updated "expected" images for screenshot tests."

Check if original expected PNGs would work on GHA.

This reverts commit 5599798.

* Revert "Revert "Updated "expected" images for screenshot tests.""

No joy - back to the updated PNGs.

This reverts commit 4cf21fd.

* dropme: is there anything suspicious in puppeteer dependencies?

* Add logic that saves actual png and diff png to the directory. From a local run I can see that that the diff comes from the black/dark gray pixels.

* fix ts-lint formatting

* update the expected images with the ones generated from my macOS. The text symbols had been slightly darker and more bold (from a chrome update I suspect) causing the pixelmatcher to fail. This now passes locally on my macOS.

* Log base64 encoding of captured images by GHA's run environment so they can be reconstructed to PNGs.

* Update expected images using the pngs generated from base64 encodings of the GHA run.

* restore .ts files back to their contents in master

* Add missing import statement and remove debug statements and TODOs.
