"Buy additional minutes" should be hidden on the storage tab of Usage quotas page
During storage quotas first iteration gitlab-org/gitlab-ce#59232 it was decided to accumulate a bit of UX debt.
The Buy additional minutes
button was supposed to be hidden on the storage
tab, but it was to complex to achieve at that time.
It was proposed to move the button inside the pipelines
tab, but a final decision was not taken.
