GitLab API change name from `builds` to either `jobs` or `pipelines`

As part of the larger name change from builds to either jobs or pipelines, we should update the GitLab API as well. The main location that references builds is the Builds API

There are a few endpoints as part of this API, but all reference a specific job and not a pipeline. As such these should be renamed to job, although the response data will reference pipeline information.

We will need to:

• Ensure the endpoints themselves are updated, for example: GET /projects/:id/builds
• Attributes are updated, for example: build_id
• Response data is updated, although this looks to correctly reference pipelines already.
