apollo_network: simplify README wording per Orwell style rules

[dan-starkware]

Prose-only edits to crates/apollo_network/README.md, applying Orwell's writing rules. No facts, numbers, or names changed.

• Cut filler comprehensive / robust / various / capabilities (lines 3, 10, 11, 12, 314, 360).
• built on top of → built on (line 3).
• Passive → active: can be extensively configured → You can configure … (262); is organized into several key modules → has several modules (303); are properly documented → Document all public APIs (380).
• comprehensive → thorough (382).

PR Summary

Low Risk
Markdown documentation only; no runtime, security, or API impact.

Overview
Documentation-only edits to crates/apollo_network/README.md—no API, config, or behavior changes.

The intro and feature bullets drop marketing filler (comprehensive, robust, various, capabilities) and shorten phrases like “built on top of” → “built on”. Configuration, architecture, error handling, testing, and contributing sections use direct, active voice (e.g. “You can configure…”, “has several modules”, “Document all public APIs”) instead of passive or inflated wording. “Comprehensive tests” becomes “thorough tests” in contributing guidelines.
