ci: Reinstate cargo sweep (#5023)
7322073d09877a92fb48f9b1136416c79eb7b24f disabled cargo-sweep from running
for turborepo workflows, but the `if` was implemented incorrectly. This was fixed in f89354f8b4f16666f98068553f302fd977153bad, but since then I've seen some other
unrelated failures, so this commit goes all the way back in time to re-enable cargo sweep
everywhere.
