Fixes #436

• Remove non-determinism in example runs, including removing all files that are greater than *.0.result. Since Bug fixes for setting default parameters #838 is merged, there should only be one result file from now on
• Allow GH Actions to commit new results to push and pull request events. In particular, those results will be stored in the file: <program-name>.ollama_ghactions.result. For locally generated results, developers should still use tests/results/examples/<program-name>.0.result. GH Actions will only generate the new file if there is variation from the expected output that is generated locally
• Removed several examples from TO_SKIP. The ones that remain include those that require set up dependencies like downloading a dataset (cldk, gsm8), building a new model (demo-halluncination), RAG examples, structure-decoding, granite-io examples, and UI examples
• See successful run at https://github.com/jgchn/prompt-declaration-language/actions/runs/14149599984
• See this run which committed new files to push event. Check out the step Update example result files
