Fix indentation in generated step definition classes

[Copilot]

Generated step definition classes had closing braces incorrectly concatenated on the same line, producing malformed code like } } for block-scoped namespaces and }} for file-scoped namespaces.

Root cause: The code generator used StringBuilder.Append() instead of AppendLine() when appending the step definition snippet, causing the class closing brace to appear on the same line as the method's closing brace.

Changes:

• DefineStepsCommand.cs: Changed template.Append(adjustedSnippet) to template.AppendLine(adjustedSnippet) in GenerateStepDefinitionClass()
• Updated approval test expectations to reflect corrected formatting

Before:

        throw new PendingStepException();
    }    }  // Block-scoped: extra spaces between braces
}

    }}  // File-scoped: concatenated braces

After:

        throw new PendingStepException();
    }
    }  // Block-scoped: proper line break and indentation
}

    }
}  // File-scoped: proper line break

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

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

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (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)
