Use renovate-bot to update dependencies
We should automate the updates of GitLab dependencies. Renovate bot is used to do this within other projects - see here for more details https://gitlab.com/gitlab-org/frontend/renovate-gitlab-bot.
These are the dependency updates we could add:
- https://gitlab.com/gitlab-org/gitlab-ui/
- https://gitlab-org.gitlab.io/gitlab-svgs/
- https://gitlab.com/gitlab-org/gitlab-eslint-config/
