OpenBrush uses an old version of ink!(3.0-rc4) and it requires an old version of cargo-contract.
You can install it cargo install cargo-contract --vers ^0.13 --force --locked.
In near future(after resolving use-ink/ink#982) we will use the latest ink! and everything should be good=)
For now, we will mark that point in the readme.
