Reconcile Cargo.toml files

Some `Cargo.toml` files in `sdk/` have descriptions that do not match their package names (e.g. [azure_stoage_blob_test's Cargo.toml](https://github.com/Azure/azure-sdk-for-rust/blob/main/sdk/storage/azure_storage_blob_test/Cargo.toml)).

Reconcile the package names, descriptions, documentation URLs (if applicable) and other metadata.

Start by reviewing the Cargo.toml files under sdk/, beginning with the linked sdk/storage/azure_storage_blob_test/Cargo.toml, and compare package names with descriptions, documentation URLs, and other metadata. Done means the affected manifests consistently describe their packages and contain correct applicable metadata.
