Event display record for tool collection

should be ready to go in
Another thing for standardisation: we have both forms in place, `CMS Collaboration` and `CMS collaboration`:

```console
$ git grep -c 'CMS collaboration'
invenio_opendata/testsuite/data/cms/cms-primary-datasets.xml:14
$ git grep -c 'CMS Collaboration'
invenio_opendata/base/static/img/opendata/ShowDocument.html:1
invenio_opendata/testsuite/data/cms/cms-tools-vm-image.xml:1
invenio_opendata/testsuite/regression/test_refextract.py:2
```
