With the quoting, we are passing an empty variable instead of no argument.
Also, if the skip is required, we are passing "-o ci.skip" instead of
"-o" "ci.skip".

Save resources and needless CI runs by skipping the trigger-gitlab job if a PR is 'draft' (can be set in the pull request page at any time) or by setting a label "WIP".
Asside from saving resources, WIP PRs that don't trigger CI are a good message to a contributers to keep testing it locally and to only get the project resources after serious testing been made on their side.
Dependabot pushes branches directly to the upstream repository. This causes
double-triggers of gitlab CI. Prevent it by running gitlab CI only for
the main branch.
