DEVPROD-13969

Description

This removes the task sync project settings and the checkbox for spawnhosts.

I'm not that familiar with the UI codebase so please feel free to nitpick or anything!

Testing

Saved settings and it worked as normal.

Evergreen PR

#8637 has to be merged after this change.

I got a failing codegen task because my codegen was based on the Evergreen PR. Should I make a 2nd PR after the Evergreen PR is merged that is redoing codegen? I redid the codegen without the changes for now

[ZackarySantana]

The type check failed but I reran it and it passed (task).

looks good to me! Don't worry about updating codegen after merging your backend PR, someone else will see it fail on their PR and will update it naturally.

Slightly unsure about the major label (but I also think it's subjective). For example I'm thinking about how the new waterfall release will probably be major, and I'm not sure if this is on the same scale.

+1, I'd go with [minor]

Switched to minor!
