WIP: Update gitlab ci (!20) · Merge requests · rc / self-reg-form · GitLab

Closed Bo-Chun Chen requested to merge louistw/self-reg-form:update-gitlab-ci into master Apr 14, 2022

Update Python version to 3.6 since most of our machine runs Python3.6, not 3.7
Update max line length to 79
Set the stage to only run on merge requests
