Fix CI jobs

[jakemac53]

This is an absolute mess now, our workspace is super fragmented at this point, but in general this:

• Fixes new analyzer deprecations
• Requires the new analyzer
  • Which requires a new SDK
  • Which requires moving more packages out of the workspace
• Fixes the jobs that run against main by allowing 3.7.0 dev SDKs. These versions will be broken at some point because the DDC binary is going to move, so we are not allowing 3.7.0 stable.

cc @scheglov do you know what min analyzer version I need for these new apis (if any)?

I think 6.9.0 should be enough, older than that not sure.
