oracle-v2.33.1: Solana dependencies: no strict versions

Cargo documentation explicitly says that restricting upper version is a
bad practice, as it makes it impossible to construct a valid dependency
tree, in a workspace that includes other crates, that might have moved
to a newer version of the dependency.  See

https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#multiple-version-requirements
