Sort feature flag environment specs and secret variables alphabetically

Problem to solve

Feature flag environment specs and secret variables (which use the same UX control) currently list in the order they were created, or perhaps a random order from the server. When looking at a long list this is not helpful as it can take a moment to manually search through and find the spec or variable you're looking for.
