Update code mods for extrude so that new top-level constants are created (#2549)

* Make sketch and extrude produce separate top-level constants

* Fix most tests

* Add a breaking test for sketch on face AST mod

* Use `extrude` instead of `part`

* Implement @Irev-Dev's branch changes from https://github.com/KittyCAD/modeling-app/pull/2472

* Get extrude on face working

* Update incorrect sketch on face test

* Update unit tests

* Fix up E2E test changes

* fmt

* Fix a couple of goofed up test updates

* More specific names for paths to node sent to modelingMachine

* Bump down playwright workers for now

* Slightly more explicit type coercion

* Update snapshot tests

* Missed one other new flow test that wasn't updated to use "sketch001"

* Typo

* Damn missed one more sorry

* A snapshot a day keeps the bugs away! 📷🐛 (OS: ubuntu)

* Re-run CI

* A snapshot a day keeps the bugs away! 📷🐛 (OS: ubuntu)

* I think the multiple sketches test reverted from under me
