Update CI to run on merge requests
CI Updates
This adds the rule: if: $CI_PIPELINE_SOURCE == 'merge_request_event'
to allow the build pipeline to run on merge requests.
The GitLab docs state "The parent project’s .gitlab-ci.yml
file must be configured to run jobs in merge request pipelines.", and this change intends to implement this requirement.
Note, that since this is not already in the parent, this will not be a noticeable change for this specific MR, only MRs post the merge of this.
