Changes

Apply upstream genkit fix to warehouses update-default-warehouse-override

Only added the affected file updated by make generate, did not include other changes (can wait till next SDK bump).

Additional Makefile changes

• Allow skipping checkout (by default it checks out the sha, which means you can't apply current fixes without going through the whole SDK bump flow)
• Bail if universe is dirty before checkout (if you have uncommitted changes in universe from experimentation, it might end up in the make generate flow)

With dirty universe:

$ echo aaa >> ../universe/README.md
$ make generate
Error: universe repo at /home/jan.rose/universe has uncommitted changes; commit or stash them, or set UNIVERSE_SKIP_CHECKOUT=1 to skip checkout
make: *** [Makefile:210: generate] Error 1

With universe checked out at master (which contains the fix):

$ UNIVERSE_SKIP_CHECKOUT=1 make generate
UNIVERSE_SKIP_CHECKOUT set; using current /home/jan.rose/universe HEAD
