[Mark-Simulacrum]

@ehuss Does this re-enable doc tests for std? If so we might want to rollup=never and prioritize it.

[ehuss]

No, this re-enables doc-tests on nightly (affects the rest of the ecosystem that uses nightly).

Doc-tests for std will be re-enabled by #73411.

@bors p=1 rollup=never

@bors r-

This is going to fail, there are some doctests that were never passing that need to be fixed

From #73536 (comment)

@Manishearth I think you may have this PR mistaken for #73411. The in-tree Cargo is not used for anything (besides cargotest, which just started a few days ago).

The macOS x86_64 job inexplicably was running 2-3 times slower than normal (based on timing data). No obvious hardware differences. 🤷
