Add sshdconfig set for "regular" keywords & clobber = true

[tgauth]

PR Summary

• note: to minimize PR size this is only intended to support: clobber: true and regular keyword (no objects/arrays yet)
• general flow of set command: create temp file based on input, validate temp file using sshd -T, back-up any existing sshd_config file (only if it is not already managed by this resource), then update/create sshd_config file
• add Pester tests

[Copilot]

Pull Request Overview

This PR implements the set command functionality for the sshdconfig resource, focusing on support for clobber: true mode with regular (non-repeatable, non-multi-arg) SSH configuration keywords. The implementation includes comprehensive validation using sshd -T, automatic backup of existing non-DSC-managed configurations, and integration of the -s (setting) parameter to distinguish between sshd_config and windows-global settings.

Key Changes

• Added set_sshd_config function that creates temporary config files, validates them with sshd -T, backs up existing configs if not DSC-managed, and writes the new configuration
• Refactored filepath handling from String to PathBuf throughout the codebase for better type safety
• Added comprehensive Pester tests covering valid configurations, backup creation, DSC-managed file detection, and error handling scenarios
