            Update to the latest version of the [Dataset Site Template](https://github.com/openactive/dataset-site-template)
          
            **Reviewer note:** Major version numbers of this library should match those of the `dataset-site-template` on which this library depends. Any updates to the dataset site template files or assets should always be a major version update in both libraries. Hence this PR, once merged, should be released with a major version bump to match its contents. Therefore, the major version number in the file `lib/openactive/dataset_site/version.rb` should be bumped in this branch before the PR is merged.
