e2e testing: refactor to remove deprecated functions

[phantomjinx]

The set-output and save-state functions are being removed and new environment variables added to replace their usage. All e2e actions use set-output so will need refactoring to update to the new syntax. See https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands and https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#environment-files for details.
