Fix pipeline failures

- Ubuntu 18.04 is unsupported in GitHub Actions so bumping remaining jobs to 20.04. https://github.blog/changelog/2022-08-09-github-actions-the-ubuntu-18-04-actions-runner-image-is-being-deprecated-and-will-be-removed-by-12-1-22/ - Conan 2 was released, which has breaking changes, so pegging to "conan<2", both in this repo, and in cnl_ci_images. - Fix linting errors that crept in while pipeline was disabled. See #1043. - Avoiding examples which no longer compile since LWG3657. - Latest Conan settings, from 1.62
