Caching GHA's Swatinem/rust-cache was not configured properly therefore caching did not happen. This PR fixes it.
cargo-contract installation step also didn't use preferences of caching. Optimization in this PR leads to reduction of this step execution time from ~20min to just few seconds.
Parallelises execution of the contracts examples build and tests which doubles workflow execution speed from ~3h to ~1.5h in case when cache is not yet created. And gives x6 speed boost when cache already in place
Replaced expensive ubuntu_20_64_core runners with ubuntu-latest, keeping execution time at the same level (build and test against Ubuntu when cache is populated is 15-16min) and slightly slower without cache (25-30min). Related to https://github.com/paritytech/ci_cd/issues/553
Tuned path-ignore lists to not trigger CI if files like README.md and so on changed.
This PR brings following optimizations to the CI:
