Subject: [PATCH] Explicitly run `+nightly` for `-Zcheck-cfg` pass in ci.
 (#12230)

# Objective

Getting this error running ci locally.

```
$ cargo check -Zcheck-cfg --workspace
error: the `-Z` flag is only accepted on the nightly channel of Cargo, but this is the `stable` channel
See https://doc.rust-lang.org/book/appendix-07-nightly-rust.html for more information about Rust release channels.
thread 'main' panicked at tools\ci\src\main.rs:166:14:
Please fix failing cfg checks in output above.: command exited with non-zero code `cargo check -Zcheck-cfg --workspace`: 101
```

## Solution

- Add `+nightly` flag to the `check-cfg` pass.

---

Obviously we shouldn't be running `nightly` Cargo, but at least now
local running of `cargo run -p ci` will pass.
