mergify: OR not supported, therefore we rely on pr-head now only ...

jenkins hooks are not always present, therefore we can't rely on them. Lets rely on
not failing for jenkins-ci hooks.

This should cover when they are not there due to smart tester, or executed and green. If failed, the condition would be false.

mergify: fix jenkins check if smart tester skips pipeline

mergify: instead of neutral, use not success neither failure

mergify: simplify needs CI transition ...

from review or work - approval and update (pr head yellow) should result in CI run. These 2 preconditions should be
sufficient to move to CI stage.

mergify: also remove needs: work if CI ready ...

There are two cases here: either PR was in  review or needs work. in any case, new
CI should be started as pr-head is yellow. Once it completes, based on reviews, we can move
to ready for merge or back to needs work if fails.

mergify: add from work to CI stage

mergify: to go to CI, work not matters if approved ...

As pr-head is neutral, means there was a push, we should test PR again and if all passed,
should be marked as ready for merge.

mergify: fix labels with spaces

mergify: add note about write access for proper review request

mergify: fix label do not merge, fixes failure with action
