feat: add test for applying with 10 open change sets

[sprutton1]

All of these test workspaces now have the test asset installed.

1. ensure the HEAD has 0 components by deleting them all and applying
2. create 10 change sets and create one of the test components
3. pop one of the change sets off and apply it
4. walk all of the remaining change sets, ensure they now have two components on the graph, and abandon them

If we merge this it'll run on all CI runs automatically and likely slow the API tests run down.

Might be worth putting it in a different folder or add a variant for a single execution in this tests folder to increase the coverage

I tuned the test down to 10 change sets and made sure it cleans up after itself. The runs looks to be sub-minute now. That cool? https://github.com/systeminit/si/actions/runs/11018151975

Perfect!
