Features

• Add Georgian translation @NorwayFun
• Add -S short option for --step in rrdtool xport @somethingwithproof fixes #1310
• Automated release workflow: a single workflow_dispatch on master computes
  the next SemVer, bumps version strings in-place, builds source tarball +
  Windows MSVC zips + RPM (AlmaLinux) + DEB (Ubuntu/Debian) — the binary
  packages install under /opt/rrdtool so they coexist with distro-maintained
  rrdtool packages without touching the system. See .github/workflows/release.yml. @oetiker
