Monthly release pipeline: Add a job to create the monthly release version

Context

One last step of every month's release is to create the version on version.gitlab.com. The release manager does this manually.

example:

By following the link on the issue: https://version.gitlab.com/versions/new?version=17.0.0 It takes us to create the version that's passed as a parameter.

Proposal

We need to automate this step by:

• creating a job to automatically create the version on version.gitlab.com
• The job should reside on https://gitlab.com/gitlab-org/release-tools/-/blob/master/.gitlab/ci/monthly/finalize-ci.yml?ref_type=heads
  • There's an API for version creation on https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/tree/main/lib/api?ref_type=heads
• There should be a rake task in release tools, executed by the job to create such version.

Milestones

• A job on the finalize-ci pipeline is created
• A rake task to create the version is created and tested
• Execute the rake task from the job
