Move jest spec helpers to own directory

See merge request gitlab-org/gitlab!51598

It is a bit confusing as we have put helpers to be used in specs in the
same directory as specs for `app/assets/javascripts/helpers`. In oder
to make the destinction a bit more clear, this moves jest test helpers
to `__helpers__` and adds appropriate readmes to both folders.

Refactor Promote Milestone Modal

See merge request gitlab-org/gitlab!51227

This refactors the "Promote Milestone Modal", replacing DeprecatedModal2
with GlModal. The way the modal is triggered, is changed from an
event-bus based solution to one which is "pure" Vue, simplifying the
code quite a bit. We moved most of the logic from the init function over
to the modal itself. Tests have been adjusted.
