Standardizes the Ruby requirement and CI across the test-kitchen org.

Changes

  • Ruby requirement: required_ruby_version = ">= 3.1" in the gemspec.
  • .rubocop.yml: standardized on cookstyle/chefstyle with TargetRubyVersion: 3.1, matching test-kitchen. Many repos still required the standalone chefstyle gem, which no longer loads — cookstyle could not run at all before this.
  • CI: unit tests on 3.1, 3.2, 3.3, 3.4, 4.0; cookstyle --chefstyle on 3.1.
  • Bundler: added the cookstyle group where missing, so bundle exec cookstyle resolves in CI.
  • Cookstyle: applied cookstyle --chefstyle -a autocorrections; cookstyle --chefstyle is now clean.
  • Dead linters removed where present (cane, tailor, finstyle, standalone chefstyle). These are unmaintained and fail on modern Ruby (cane calls File.exists?, removed in Ruby 4.0; tailor needs ostruct, no longer a default gem). Cookstyle supersedes them.

Comment/config changes plus mechanical style autocorrections; no intentional behavior changes.

- Set required_ruby_version to ">= 3.1" in the gemspec
- Standardize .rubocop.yml on cookstyle/chefstyle with TargetRubyVersion 3.1
  (the standalone `chefstyle` gem no longer loads, which broke linting)
- Run unit tests on every Ruby release from 3.1 to 4.0 and run
  cookstyle --chefstyle on Ruby 3.1
- Add the cookstyle bundler group where it was missing so
  `bundle exec cookstyle` resolves in CI
- Apply cookstyle --chefstyle autocorrections
- Drop dead linters (cane, tailor, finstyle, standalone chefstyle) that
  are superseded by cookstyle and fail on modern Ruby

- Add the standard .markdownlint.yaml / .yamllint configs where missing
  (repos without them fell back to strict defaults and failed CI)
- Exclude CHANGELOG files from markdown-lint in the shared workflow, matching
  test-kitchen; generated changelogs cannot satisfy the rules and are rewritten
  on each release
- Fix real YAML indentation (sequences must be indented under their key);
  verified the parsed YAML is unchanged
- Remove dead .travis.yml / appveyor.yml configs, which were also the main
  yamllint offenders
- README cleanup: drop obsolete <a name="..."></a> heading anchors and dead
  travis-ci.org badges, modernize .png badge URLs, fix heading levels, add
  code-fence languages, repair broken lists, strip trailing whitespace

- Remove Code Climate badges
- Fix dead documentation links (docs.kitchen-ci.org and old
  downloads.chef.io/docs.chef.io paths are gone; ChefDK is superseded by
  Chef Workstation), and repoint chef/* GitHub links at test-kitchen/*
- Replace the "enter-github-user" placeholder links left over from the
  gem template
- Point LICENSE links at the branch and filename that actually exist
- Normalize the gemspec license to the SPDX identifier "Apache-2.0" so it
  matches the shipped LICENSE file

- Drop the chefstyle bundler group / dev dependency. chefstyle pins an old
  rubocop, which resolves cookstyle down to 7.x where "cookstyle --chefstyle"
  is not a valid option. Cookstyle supersedes it.
- Remove .cane config files; cane is unmaintained and calls File.exists?,
  removed in Ruby 4.0
- Remove the bundler dev dependency; bundler ships with Ruby and pinning it
  only constrains resolution
- Add the gem version badge to READMEs that were missing one

- Use `gemspec development_group: :test`. Gemspec development dependencies
  otherwise land in bundler's :development group, which CI excludes via
  BUNDLE_WITHOUT=development, so rspec/fakefs/rake were missing at runtime
- Add base64 where cucumber 9.x needs it; it is no longer a default gem on
  Ruby 4.0
- kitchen-opennebula: fog-opennebula's latest release is 0.0.5, so ">= 0.1"
  could never resolve
- kitchen-rackspace: port the driver off Kitchen::Driver::SSHBase, removed in
  test-kitchen 4.x, and wait via the configured transport instead
