We don't run style checks on our CI, even though we have a '.clang-format' setup in the repository. Let's add one, the job will validate only against the new commits added and will only run on merge requests. Since we're introducing it for the first time, let's allow this job to fail, so we can validate if this is useful and eventually enforce it.
For GitHub, we allow the job to pass by adding 'continue-on-error: true' to the workflow. This means the job would show as passed, even if the style check failed. To know the status of the job, users have to manually check the logs.
For GitLab, we allow the job to pass by adding 'allow_failure: true', to the job. Unlike GitHub, here the job will show as failed with a yellow warning symbol, but the pipeline would still show as passed.
Also for GitLab, we use the 'CI_MERGE_REQUEST_TARGET_BRANCH_SHA' variable by default to obtain the base SHA of the merged pipeline (which is only available for merged pipelines [1]). Otherwise we use the 'CI_MERGE_REQUEST_DIFF_BASE_SHA' variable.
