[codex] Fix SG-5 style guide examples

[NWarila]

Summary

• Re-sorted the SG-1 ConvertTo-Thing and Get-Thing example [CmdletBinding(...)] options into SG-5 alphabetical order.
• Kept the change docs-only; no analyzer, settings, or PowerShell source files changed.

Validation

• STYLE-GUIDE SHA-256: C0CB352A1EBA9AC56C963F276C3899A94EB4195FA97DC01C031CBBC5B9F5BE88 (byte-identical with exporter mirror).
• Example scan: all guide example CmdletBinding/Parameter named arguments are alphabetical.
• ./tests/Invoke-Tests.ps1 -MinimumCoverage 80 under Windows PowerShell: 31/31 passed, coverage 89.29% / 80%.
• Template analyzer job equivalent under Windows PowerShell: Invoke-ScriptAnalyzer -Path . -Settings PSGallery -Recurse found no issues.

Note: local pwsh is not installed on this machine, so the template CI commands were run under the available Windows PowerShell host.
