Waive credit card validation if project has paid CI/CD minutes

Previously users working on a namespace on a free plan would generally
be required to add a credit card if they use shared runners. However,
free namespaces are not really free if the owner pays for add-on CI/CD
minutes. In these instances, we should treat these namespaces as we do
with Ultimate/Premium and not require credit card validation for users
who use them.
