Gitlab-CI fails on build for php7.2

[jordonedavidson]

When using the default gitlab-ci configuration the build fails for php 7.2

Steps to reproduce:

• Scaffold new project using gitlab-ci integration
• Commit code to gitlab repo
• Test fails.

The following output is recorded:

Running with gitlab-runner 12.3.0 (a8a019e0)

ERROR: Job failed: Error response from daemon: manifest for tetraweb/php:7.2 not found (executor_docker.go:188:0s)

The Problem: there is no tetraweb/php:7.2 image.

It appears that the tetraweb project has been abandoned for a year. The latest php version available is 7.1

Solution: Use a different image.
