Add workflow to verify Python example builds (#245)

* Fix more us artifact registry references in lock files

* Create GH workflow for python examples

* Clean up python workflow file

* Trivial change to test the workflow rule

Plus this actually fixes a typo

* Also omit these new dirs from the web builds (they truly don't affect them afaik)

* Another trivial testing change

* Add workflow file for Java example (#247)
