Update nokogiri to 1.18.3

See: https://github.com/sparklemotion/nokogiri/releases/tag/v1.18.0

- required for ruby 3.4 compatibility
- add more platforms to lockfile to support
  docker build process, due to changes
  in the nokogiri native gem setup where
  -musl and -gnu linux platforms are no longer
  interchangeable
- bundler >= 2.5.6 required according to Nokogiri release
  notes, so updated to current latest version (2.6.5)
