[tmadlener]

BEGINRELEASENOTES

• Remove macOS workflow since github hosted runners no longer support all necessary features. See also: Make ilcsoft workflow to use an existing nightly build and remove mac workflow AIDASoft/run-lcg-view#3
• Update used github actions to latest available version for better caching behavior and cleaner log outputs
• Switch to newer LCG releases for the build environments to target more recent compilers and python versions.
  • Keep one build environment that is close to the one used for the iLCSoft v02-02 to avoid accidental breaks.
