Items: Modify calculate-tests-coverage-on-pull-request workflow

[MDI74]

Need to modify calculate-tests-coverage-on-pull-request workflow
So that the pipeline falls if the tests fail.

Description
Now, if the tests fail in the calculate-tests-coverage-on-pull-request pipeline, it will still continue its work and be successful, and the percentage of test coverage will be calculated incorrectly. This can be misleading.

Value

• Always get the correct test coverage values
• See errors in devcontainer configuration (tests are run using the devcontainer configuration)

Definition of done

1. Pipelines fall if the tests are executed with an error
2. If pipelines fall, test coverage is not recalculated, and the report on test coverage is not compiled
