Cypress. Fix/update case 69.

Motivation and context

Recently, the test has been falling more often. For this reason, an additional check of the visibility of the drop-down menu has been added.
The test has been finalized and adapted to the current changes in the develop branch. The function of getting the job number has been redesigned. Added state or stage installation functions for jobs.

How has this been tested?

maybe merge develop will help?

It seems to have helped. The problem is in action jitterbit/get-changed-files@v1. To solve this problem, I have prepared PR
#4079 (applied the recommendations specified in the actions repository in the issues section).
