chore(deps): specify openzeppelin version 4.9.3 for reproducible builds
The code couldn't compile because it was using a version of
`Ownable2Step` that introduced breaking changes.

This commit sets the used version to the latest stable release of OZ,
which is 4.9.3. Hence the usages of `Ownable2Step` needed to change as
well.
