ci: address review feedback and fix bundler-cache test failures

- Move `Fix dependency for libyaml-dev` before bundler-cache steps in
  benchmark.yml so psych v5 native extensions can build during cache miss.
- Add explicit `cache-version: precompile` in precompile-check.yml so all
  workflows set the cache-version key consistently.
- Add `BUNDLE_DISABLE_CHECKSUM_VALIDATION: 'true'` to the job env: in all
  three pro-integration-tests jobs to match pro-lint.yml and
  pro-test-package-and-gem.yml when bundler-cache runs `bundle install
  --frozen`.
- Override `BUNDLE_FROZEN`/`BUNDLE_DEPLOYMENT` to false in the
  `dummy_no_turbolinks` rake task. The task removes turbolinks from the
  Gemfile via the `DISABLE_TURBOLINKS` env var, so the lockfile diverges
  and bundler-cache's frozen mode refuses to load.
