Control-plane pipeline should update pipeline before running pushing `paas-templates` changes

[o-orand]

Expected behavior

As a COA user, when

Observed behavior

We add a new dependency in deployment-dependencies.yml on paas-templates,we commit and push it. It triggers an new job in the appropriate x-depls-update-generated pipeline, and it generates updated pipelines in coa/pipelines/generated/<team-name>/<root-deployment>, and commits it to config-repository. Unfortunately, sometimes the commit on paas-templates is processed before pipeline update (ie: push-changes is executed before load-generated-pipelines)

Affected release

Reproduced on version 3.2.2

Traces and logs

[o-orand]

It occurs when deployment-dependencies is updated (sequence of addition/deletion)
