firewalld var name prefix (#19)

Changes:

- Update variable names for the `firewalld` role in the molecule tests
- Update some details in `galaxy.yml`

After UCL-MIRSG/ansible-collection-infra#35 is
merged I propose creating a new release of the `mirsg.infrastructure`
collection (`1.3.0`) and pinning the version number in
[meta/requirements.yml](https://github.com/UCL-MIRSG/ansible-collection-xnat/blob/33413301671dcca18388f13a91ec363c9ce07539/meta/requirements.yml#L10)
in this PR.
