Update dependencies

* Bump tss-esapi to the latest version to get rid of dependencies conflicts with KMS SDK
  (More details in parallaxsecond/rust-tss-esapi#519)
* Bump AWS SDK dependencies to their latest versions (within possible MSRV=1.68.2)
* Move aws-config to dev-dependencies because it's used only in tests
* Bump the crate version itself
