fix: Broken tests + upgrade to Blockly 12.0.0. (#527)

* fix: Broken tests + upgrade to Blockly 12.0.0.

* fix: CI workflows.

These correctly link against develop for v12 tip-of-tree, instead. This
also includes some renaming in/of the workflows for clarity.

* fix: Actually link against 12.0.0 not beta.7.

* chore: Revert 12.0.0 naming.

Using 'v12' is more generic and will automatically be correct when the
plugin moves to an eventual 12.0.1 or 12.1.0.
