Utilize a temporary version of the gemnasium-python image that support python 3.9
The default version uses python 3.6, and that doesn't work with Wellbore Domain Services. So, we upgrade to this temporarily provided image until GitLab produces a new default, which is slated for version 15.0.
After GitLab produces a newer default image, these changes should be removed.
