Update to edition 2021 on master (#3028)

Objective
During work on #3009 I've found that not all jobs use actions-rs, and therefore, an previous version of Rust is used for them. So while compilation and other stuff can pass, checking markup and Android build may fail with compilation errors.

Solution
This PR adds `action-rs` for any job running cargo, and updates the edition to 2021.
