check-substrate job fails due to displaydoc issue with the latest Rust nightly compiler #1105
Description
Summary
Context: #1099 (comment)
The check-substrate job for no_std check relies on nightly channel, which fails when running with latest nightly > 2024-02-27 compiler that accepted rust-lang/rust#120393. This should be resolved in yaahc/displaydoc#46.
As a temporary solution, we've set the NIGHTLY_VERSION to nightly-2024-02-24. It's worthwhile to explore whether it's essential to perform the no_std checks on the nightly channel.
