Revert "[cv][dev] reduce potential blast radius before the CL purging is deployed."

This reverts commit 0e5df3a92f1ed2c8aa3361a0d82047fd69fe2fe7.

Reason for revert: autoroller is blocked, and I don't
want this auto-deployed to -dev while I'm away -- I want to be there
to debug cq-test issues.

Original change's description:
> [cv][dev] reduce potential blast radius before the CL purging is deployed.
>
> CL purging is the first action that **may** (but shouldn't) cause harm.
> Furthermore, -dev is autodeployed.
> So, remove big projects from -dev before landing full purging pipeline.
>
> Finally, enable `cq-test` project on -dev.
