Fix async method naming convention in code example

[Copilot]

The documentation in async-scenarios.md states: "Add 'Async' as the suffix of every async method name you write." However, the code example contradicted this recommendation by using GetDotNetCount instead of GetDotNetCountAsync.

This change updates the code example to be consistent with the documented best practice by:

• Renaming the method from GetDotNetCount to GetDotNetCountAsync
• Updating the method call in the Main method
• Updating the comment that referenced the old method name

The fix ensures that the code example properly demonstrates the async naming convention that is recommended in the documentation.

Fixes #43830.

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• learn.microsoft.com
  • Triggering command: /home/REDACTED/work/docs/docs/docs/csharp/asynchronous-programming/snippets/async-scenarios/bin/Debug/net8.0/async-scenarios (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This LGTM and I'll now.
