Sort Revisions in Rollouts by newest first

[gnunn1]

Currently the dynamic-sdk-console does not support providing an alternative default sort order for VirtualizedTable, RFE open here:

Hacked around this by reversing the sort order for the revision column, the UI arrow won't match the sort order but at least the default sort order will be correct.
