Typo Update rust-client-tutorial.md

"This section tutorial will guide you through using the most common RPC endpoints with..."

The word "section" is incorrect here. It should be:

"This tutorial section will guide you through using the most common RPC endpoints with..."

This change ensures the sentence flows correctly and makes more sense grammatically.
